Mountain kaasht follow a variety of religions, some stemming from remnants of religion before the Time of Madness and some not. Often being isolated by their habitat and climate, the ancient Mountain kaasht clans have in many cases turn to the spiritual for solace. The more obscure religions are often tailor-made for their individual clans, but some are well-followed enough to be documented and well-known by other kaasht breeds. On occasion other kaasht breeds even are accepted into these religions.

The most common is, of course, the all-kaasht following of the Color Spyral and reverence towards the three moons of Tryne. Of the less common but still prevalent religions in the mountains are three major followings: Mraakaasht (ancestor worship), Anumraa Horoon (a polytheistic religion), and Wreamra Horoon (a monotheistic religion).

Mraakaasht
Mraakaasht, called by scholars Mraakii Kaasht se maa Horoon or "divine kaasht of the mountain", is the most common of the uncommon, in a sense. Almost every Mountain kaasht highly respects the kaasht who have come before him, a natural outgrowth of his love of tradition and family. The next step into ancestor worship is a simple one to take and many kaasht have taken it. Many Mountain kaasht homes boast a well-tended shrine to ancestors, whether with specific names in mind or all ancestors in general, and it is a part of many a Mountain kaasht's routine to stop and offer a prayer for guidance or strength to their predecesors. Amazingly enough, this religion even offers some evidence in the form of rare visitations or boons granted by spirits of the dead.

Ancestor worship has no set territory on Tryne and no specific environment it is most common; it can be found anywhere there are Mountain kaasht. This is a religion that has little qualms about proselytizing kaasht of other breeds. Also, it is common for a follower of Mraakaasht to also follow another religion, be it the Color Spyral or something else.

Anumraa Horoon
The polytheistic religion, named Anumraa Horoon by researching Plateau kaasht, is a remnant from before the Time of Madness, preserved in a very skewed, splintered fashion from veneration of the Elementals. Its name is a shortened version of the more specific but much longer "Anu Mraakaa se maa Horoon" which translated into "Many gods of the mountain". Deities have been assigned to certain aspects of nature, a relatively understandable characteristic as a Mountain kaasht is often at the mercy of nature. Depending on the clan and individual, the number of these deities is wildly different, but in nearly every sect these remain the same: Life, Earth, Fire, and Wind, also known as Air. Other common elements deified are Water, Ice, Death, and Metal.

The center for this faith is Duuskeev, a Mountain kaasht city of mainly mercenaries, and it commonly preaches fending for one's self while still offering thanks to the gods for whatever successes one might stumble upon. Very few non-Mountain kaasht follow Anumraa Horoon, though other breeds have something similar.

Wreamraa Horoon
The monotheistic religion, called Wreamraa Horoon, is based on rare sightings and sensings of the Earth Elemental. It's common name is shortened from "Wrean Mraakaa se maa Horoon", or "First god of the mountain". The only physical aspects of the great being agreed upon are its immense size and magical presence, but all kaasht agreed that it must be the patron deity of the mountains. It immediately became the patron of the Mountain kaasht, as well, and the center for its worship is in the hidden city of Mraakii Eevuu.

Generally kaasht of this faith preach peace and acceptance, often with the characteristic lack of peace and acceptance that Mountains are famous for. Sometimes, however, a true follower will rise to power who practices what he preaches. Only very rarely will a non-Mountain be converted to Wreamraa Horoon, in large part due to the secrecy surrounding several of its main practices, but if a kaasht of another breed is involved it is more often than not a Cave. The deity itself is attributed powers over life, death, nature, and, of course, the mountains, and generally described as a massive but gentle creature with endless love and compassion.

The latter two faiths are active rivals. Those following Anumraa Horoon see their monotheistic cousins as narrow and spiteful while those following Wreamraa Horoon see their polytheistic cousins as heretical and far too liberal. In reality, much of the insult hurling is the pot calling the kettle black, though the two factions are very rarely physically violent, as Mountains prefer to debate and argue than claw at each other.
