Ashley Williams. From Evil Dead. But a woman, so his-erm - HER name can actually be used (because if you didn't know Ash is short for Ashley, yeah). 

She's a Supporting Character and has a fair amount of lines. With this being a SAMSS Machinima, I have no opinion on if you're Female or Male or whatever. I (male) voiced a teaser line for her at the end of Part 1 (but we can just make a joke where something got stuck in her throat and that's why she sounded different).

She's come to Coshoems to find Slashers to kill. That's esstsiently it.
