Feral beast race?

[Kyuuen]

Unfortunately, as far as I'm aware, it's written into the lore that beast tribes can't be playable races due to the whole Warrior of Light thing and beast tribes cannot be warriors of light, since each beast tribe has a primal attachment to them (often one group for, one against said primal), but their fates are intertwined. As a result, adding a feral beast race would work in a similar vain to beast tribes and would therefore break a lot of lore.

Don't think that's enough of a reason, considering the events of Baelsar's Wall. That is unless you want to start considering Hyur as some sort of Beast Tribe. =P
