Speculating about the Archaic Elevated Caste...

[Petike]

hmm... That actually makes scene. The Archaic might reappear in Lux Tenebras

Oh, all right then - if Penumbra and Lux Tenebras are set in the same "universe", just different time period, we might pay the Archaic Caste a visit to uncover more of their secrets.

Hehe, hope they won't become the staple antagonists of the possible future "Frictionverse" (a unifying world where Frictional's games are set)... ;-)
