Now in Wraith the Oblivion, wraith's had to battle their shadow. So, this was technically Luca's shadow when he was created and roleplayed; however, everyone including myself forgot about this mechanic of the game. Honestly, if I ran a Wraith game I'm going to homebrew shadows to either work as similar to a vampire's beast mechanic in VTM20 or the werewolf's rage mechanic in WTA20.
