a. 7
b. Same character each time...
c. Fantasy (Funny concept actually: I stick out like a sore thumb; I'm the only pirate on a 16th century battlefield. So in a clash of armor, shields, and large swords you'll see a rough frock coat and a cutlass. Aye I be representing )
d. A bit of both, I mostly re-enact for escapism. PM me if you need me to clarify.
