"It absolutely should not be able to, no," Luther says, looking mildly alarmed. "If it were able to--if Gwyn was genuinely on to something, rather than merely afraid or worried--then we should all be very concerned.

Laerdya and Andry were the driving force behind bringing the aboleth here, and Gwyn knows neither are bent on doing evil. Nor can I imagine that she would think either were under its influence; she's known them all her life and would be well-equipped to see whether they were experiencing personality changes. They have not," he adds. "Well, Laerdya has, but only since Gwyn's kidnapping and only in ways one might expect from that trauma."
