Welcome to Slidr River Valley, home to the strong, the brave, and the resilient. Challenging the odds surmounting against them, the Houses of equine fight in a power struggle for ultimate control over the Valley. With the Bloodless fading away after the First Great Winter of Three, Fimbulvetr, the Slidr River Valley is in a state of discord as the Houses throw themselves into an arms race for power. From predators to the gods themselves every day ushers in a new obstacle to overcome. Fimbulvetr is a literate intermediate-advanced fantasy horse role-play with a survivalist concept. The environment is designed to work against your characters as they move forward in their journey through the arcana riddled realm of Slidr River Valley. With an immense history and lore, we encourage our members to create locals and "outsiders" alike.

Summer Year One | The sun is high and it is long, and with it as are the days. Summer has claimed the entirety of the Slidr River Valley and in doing so has cast higher, comportable temperatures throughout the Southern and Central territories. The Western still boasts snow capped mountains, but mud slides are frequent and they are heavy. The North remains green, just warm enough to cultivate and brood the new life there, but the further you tred the lower the temperatures fall, their mountains still ice cladden and snow tipped. The East, the poor souls, is sweltering. At night the temperatures drop to the Valley's daily warmth. Little can be done to add comfort, and each day the Oasis becomes drier and drier...

Credits | FAQ

  • Q: What is Fimbulvetr?
    In Norse mythology, there are three great winters that lead up to Ragnarok. We decided to base our site off of this concept, and many other aspects in Norse mythos, because the events that lead up to the big finale are often more interesting than the finale itself.
  • Q: Can you teach me to role-play?
    Yes, we will teach you, but please respect our minimum word count of 250. We're always willing to help!
  • Q: Do we join with one or multiple accounts?
    We are a multi-account site with the accounts linked together.
  • Q: What about vampirism/cannibalism?
    Cannibalism is very much accepted. Herbivores are actually known to eat meat on the rare occasion. And hell, if your character wants to drink blood, let them drink blood, but please realize they are not an actual vampire and cannot infect others.
  • Q: Where is the valley located?
    Let's assume somewhere temperate, but as this takes place in an AU "Earth", geography of the continents is slightly different.
  • Q: What's the difference between the houses?
    There is no difference among the houses, except for their preferred console. Tryggr supports xBox while Ambrosius backs Playstation. Vromme plays on the Wii. In all seriousness, the houses have a few minor differences but in no way are they like lights/darks that have defined characteristics for being in said house. They also change per sovereign.
  • Q: How superstitious are the local character?
    Some are very superstitious while others are just a little-stitious. Kidding, it is entirely up to their role-player, while the main body of locals tends to be rather concerned with superstition.
  • Q: How do new equines get into the valley?
    All Outsiders must cross the Bifrost, a large cave system delving beneath an ancient and great tree of mighty proportions. After navigating the maze-like roots, characters must then cross the series of natural bridges made of stone, fallen branches, and roots to the actual valley. The rest of the realm is either impossible to traverse or shrouded in mystery/undiscovered. It is unknown what lays beyond the mountains in the Further East (land of the exiles) as the volcano makes it very difficult to explore.
  • Q: Does my character have to be apart of a house?
    No, but being nonpartisan is extremely dangerous. If the nonpartisan population becomes too big, then one or two (or however many we feel like) nonpartisan will be killed randomly every in-game year until the population decreases. The reason is not having the protection of a house makes the character very vulnerable.
  • Q: What's the deal with exile?
    It's where the bad boys go to play. Being in exile sucks. You're stuck on this tiny little oasis on an active volcano in the middle of no where. It sucks. But it's fun.
  • Q: Can my character be a sovereign?
    If positions are open, then yes! Otherwise, you will have to challenge for an occupied throne.
  • Q: How does my character become a Jarl?
    If the royals in your particular house deem your character worthy of being a Jarl. Or, a character already belonging to a house can accrue two followers and take a vacant herd land in their House's holdings.
  • Q: What are aristocrats?
    They are blood relatives of Jarls, and therefore receive or expect a higher form of respect.
  • Q: Can my character join the guard/kingsmen?
    Yes! Being in the guard is an awesome thing. SWP's will need plenty of kingsmen and guards in the future.


  • Q: How did the valley form?
    Long, looooooong ago there was Yggdrasil, the tree of life. The tree came into bloom and produced many seeds. Some of these seeds found fertile soil in the cosmos and began to grow, forming new trees. This is the start of the Slidr River Valley. For many eons the valley was separate, alone in this multiverse. The mother tree, Yggdrasil, began to entangled with her young seedlings, linking them to her and vice versa via the Bifrost. If one happens to come across the Bifrost, they may find themselves in a new world, the Slidr River Valley.
  • Q: Why does Espen protect Ambrosius (for now)?
    Espen has been here far longer than any of the equine communities. In his eternal sleep, he is still omnipotent to what occurs in his hold, and therefore will awake to any violence shed on his lands. Ambrosius has, essentially, taken advantage of this fact.
  • Q: How was Dehaan able to kill Thror then?
    Good question! Over the centuries, as Ambrosius grew as a house, they claimed more and more lands as being part of their hold. After the creation of Vromme, Ambrosius kept the western and northern lands for themselves. The southern territories were given to Vromme. The western territories that Ambrosius had claimed were in fact not part of Espen's territory, and thus, Espen did not protect those lands. Thror and Fredrekke were strolling together on the border between the western and northern territories when Dehaan struck. Unluckily (or luckily), Thror was on the western territories when he was slain, and thus, Espen did not intervene. Had Thror been within the northern territories when Dehaan attacked, then Espen would have torn Dehaan apart for spilling blood on his lands.
  • Q: How did Dehaan conquer the western territories?
    For centuries the valley has mostly been at peace, and due to having Espen protect half of their lands, Ambrosius never formed a strong army or guard. Thus, when Dehaan gathered a strong army, he was able to quite easily take over those lands. He strategically took over the territories Espen did not claim as his territory.
  • Q: Can Ambrosius form an army?
    Ambrosius can form an army! They simply have not in the past because of the relative peace. When war threatens, they are free to start forming an army (or not). However, they need to remember that no blood can be spilt upon their lands or else lose their right to reside within Espen's territory.
  • Q: Fredrekke has been around a loooooooong time, no...?
    Yup, Queen Fredrekke of Ambrosius is an old fart. So is the blessing or curse of being a Spiritborn.
  • Q: Is The Bloodless still around?
    Good question! We assume so but who knows ???? ¯\_(ツ)_/¯ No one has seen him since the First Great Winter ended.
  • Q: How much time has elapsed since the end of the First Great Winter? Is there a general timeline?
    Roughly 25 years has elapsed since that time. Only the eldest recall those events now. 35 years ago the start of the war between Ambrosius and Tryggr. 30 years ago the war ends and a decade of plague, curses, and decay looms over the valley. In the final year, the valley experienced a winter that lasted and lasted. 25 years ago The First Great Winter ends after The Bloodless intervened.


  • Q: What are crystals?
    For every IC post, you will receive a certain number of crystals. These can be spent at the Outpost or buying graphics from members.
  • Q: Can I role-play predators?
    Yes, you may role-play predators.
  • Q: What about spirits?
    No, we have special accounts for the spirits.
  • Q: Can my character have a pet?
    Yes, you may but only through a purchase at the Outpost.
  • Q: Does my pet help my character in fights?
    No, sorry, not in official challenges! It'd be pretty unfair if a bird helped one character and a wyvern another, now wouldn't it? For spars and battles where the staff do not decide the winner, however, feel free to do as you please.
  • Q: How does my character get out of exile?
    You usually don't. Either you get out of exile either by dying or being pardoned by a royal.
  • Q: What actually is the Bifrost?
    A giant (like GIANT) tree that equines must traverse the root cave system of to enter the Slidr River Valley. The area surrounding it is covered in a everlasting mist, so it's hard to tell what is across the ravine that our mighty tree sits upon. You may come across these misty vales anywhere, as the Bifrost picks and chooses who to test.
  • Q: So wait... Espen will kill you if you attack/kill in Ambrosius holdings?
    Yes. The God-bear does not take kindly to blood being spilled upon his territory. So. If you have a temper, you may want to bear (haha!) that in mind. Go ahead and test it.
  • Q: Can my character start out with an arcana? Technically, no. While you may have filled out your Arcana tiers on your profile prior to acceptance you do not start at apprentice where you can use your magic. Your character can easily harness arcana prior to entering the Bifrost, but the tree essentially "dampens" or "blocks" your powers for a time and you have to relearn how to use them.
  • Q: Why do Spiritbornes get certain arcana levels and others don't?
    They are very powerful creatures, being half-spirit and all that amazing stuff. They are able to perform greater feats and harness more powerful arcana.
  • Q: Why can't anyone leave the valley?
    The valley is said to be encircled, protected, or imprisoned (depending on who you talk to) by the serpent Jörmungandr. He works alone protecting the borders. This is not to be confused with the Bifrost: it chooses who is strong enough to enter the Valley, and Jörmungandr will find anyone trying to leave.
  • Q: How do characters help others in the Bifrost if they can't leave?
    Simply put, the Bifrost selects your character to come in to aid. It is a mysterious force that allows you to venture so far in, but prevents you from leaving entirely. Think of it as a ever shifting maze.
