I realized I probably should have mentioned you for this question. To refine it I was thinking of being tied to Alando and maybe the primordial transformation.

I had a character concept in mind that would use the warforged mechanics combined with the specter transformation. Basic idea would be a character hodgepodge-ed together from the wreckage of ships and fragmented souls of fallen sailors by a chaotic primordial/aberration. The character's driving purpose being developing a sense of self and purpose. Would this be an appropriate path to pursue mechanically and for the setting?

Looking at the demographics of Diamond Lake mentioned in the player's guide pdf, I'm wondering how accepting the townspeople, and people in the general vicinity, are of the more beastial/monstrous races?

Is it ok to re-fluff class abilities? Specifically, I was thinking of re-fluffing a barbarians abilities to be alchemical in nature (mutagenic warrior-ish)
