Given Lanque's whole Alquemist deal, crave for eternal life, and being life bound. Maybe his class could be a Maid or Sylph of Life? Or even Thief but I doubt it given Condy is around.

Classpects aren’t necessarily restricted, it’d be interesting seeing someone with the same Classpect as Condy. Maid or Sylph are potentials, but I’ll hold off my judgement until we actually know ANYTHING about these characters.
