- Development Gag: Nictotraxian first appeared in one of Dire Wolf's other projects, Clank!, a Tabletop Game which takes place in the same setting. Players use a Deckbuilding Game mechanic to move around a traditional game board, attempting to loot treasure from Nictotraxian's hoard without getting caught, but every time they make noise (the eponymous Clank), the odds that she will catch and hurt them increases. Nicto's voice line in Eternal:Nictotraxian: Clank, clank, thief. I can hear you...
