Like the other tribe write-ups, I appreciate the details on Kypiq and I think certain parts make the tribe very unique. However, I think this tribe will be very difficult to play. A lot of their benefits sound good on paper but in a game, most first-person games, at least; they'll be under-powered and challenging.
They are certainly the most biome restricted so far. Disguises won't be of much help if you know Kypiq are your enemies, reflective eyes will reduce stealth, and cleverness is a player skill and very hard to augment in a game - in fact, how does "being clever" benefit a player?
They'll have powerful enemies I expect and only a solid alliance with the Neran will ultimately keep them safe. The few benefits are animal friendliness (so an increased survival within the biome), a valuable trade commodity (silk), accelerated alchemical skill, and minor technology advantage (albeit with leaves and certain wood). Again, i think this will be a challenging tribe to play. However, in spite of this, this tribe is one I'm sure many will want to play.
