I might be interested, but I'd like to know:

How often do you want players to post?

Can you give us a glimpse of this alternate history before we confirm interest?

Is this roleplay based around a small group of travelers, then, or individuals doing things around different parts of the world?

If it's based around a small group of travelers, is there a reason they'll want to stick together rather than separate due to conflicting cultures, worldviews and potentially religious friction?

I'm a huge fan of alternate histories, but I'm honestly not sure right now how often I can dedicate to posting if I join another roleplay. That said, I do have a character concept in mind already (an old Moorish warrior that's tired of the wars in Iberia), but I'd like to know the answers to these questions first.

EDIT: Alternative concepts, by the way, include a Moorish scholar and a bandit from the Black Forest in Germany.
