I highly doubt that, Skab seems to be a totally original character (unless you picky people want to call him a meat rip-off). I think hes closely tied with the Dragon King... perhaps one of his soldiers from his undefeatable army.

Yeah i first thought that we would've been a warrior of the Dragon King, from the undefeatable undead army.

I guess I am just too curious about the zombie idea and throwing wild things out there...but still it's a possibility....
