So far, I've figured out the following:
- Ple-Sen is not a Sage;
- Nefela is not a Sorceress;
- Nebo is not an Adept;
- Lizard is not a Keymaster.
It's still unclear about the Reaper.
The same goes for the others.
- Amko is not a Spellcaster, Keymaster, Sage, Sorceress, or Adept;
- Lizard is not a Spellcaster, Sage, Sorceress, or Adept.
