Heroes 6 - Discussion

Well, I don't know. LaBoule mentioned the 5th faction, saying that, yes, it's new to the series, but the titular race was present in previous installments (as a biological species:), although it has mutated somewhat compared to previous parts. This faction will have 3 female creatures. The faction will be non-humanoid (a hint against Dungeon). When he talked about the racial ability of the 5th faction, he used the word stream. I can't give the exact quote.
Oh, and it was also noted that Sveltana's mission with Mother Namtaru takes place on the Naga islands.
