1. A short sketch of your character's backstory.
In the Alias. I kept where his museum is and what relics he has collected deliberately vague. Those details can be decided later.
2. What do you want from a GM in a PbP, and from other players?
I've been in a lot of PBP games. I find that the ones I enjoy most are always the ones with a cohesive and interactive group who all have strong writing ability. With that as a foundation the game will be great no matter what its about. From a GM, assertiveness is my number one desired trait. I find that GMs willing to roll initiative and saves for players rather than wait, NPC absent players quickly, and generally keep a game's momentum up, those GMs have my absolute loyalty.
3. What do you do for fun when you're not on the Paizo boards?
I work for a security company as a dispatcher. I am also an actor and a stage combat choreographer. Other than that, I read a lot and spend way too much time trying to clean cat hair off myself.
4. A taste of your writing.
I'm afraid I didn't get into the thread quick enough to participate much. You'll just have to take my word for it that I'm a very competent writer and a dedicated player. Or you can read this.
5. I'm considering using the mythic playtest rules for this...
Seems like a good fit for the setting and story. I completely understand your apprehension though. Either way is fine with me.
