Four.
My human fighter first PC who permed, my loooooong running elf mage, a dwarf fighter for when I want to be loud and hit someone and a dog scavvy joke character (who may actually be the dumbest character in the alliance).
I really only tend to primarily play one for the most part. Back when I played two chapters regularly I'd play the elf at one and the dwarf at the other, but old age and adult responsibilities have slowed my LARP roll so only the elf sees much daylight anymore.
