I recently retconned Jerec into an Ithorian but left everything else about him the same. It was an excellent choice. Have a nice clear look at some familiar and maybe less-familiar faces.

Houk

Wookiee
  • Hook: The Wookiee homeworld of Kashyyyk has seen some crazy things, including a devastating One Sith invasion fifteen or twenty years back. Since then there's mostly been peace and stability, though the presence of the Jedi temple called Silver Rest has drawn all kinds of raids and similar fuss.

Arkanian
  • Hook: These simple little humans have been running things for far too long.

  • A useful non-SW picture base: Elric of Melniboné or pretty much any other depiction of an albino human.
