Kyra
Looking with her true seeing at the misty corridor, she tries to gleen its magical nature as she says, "I would not touch this mouth, nor go near the face, for it emits a great deal of necromantic magic. Perhaps it may be part of Acerak's phylactery, but I doubt a wise and powerful lich would put that here." She then says, "I can summon another construct and send it through the mist and see what it sees. However, I am unsure of the magic the mist may have."
Edit: "Also," Kyra considers aloud, "we haven't checked for any secret doors and passages down the hall, have we?
ooc: Kyra was doing that as she passed, as an elf, that is.
