Taalia has a pre-apprentice level of grasp of the formal study of the winds of magic; and there's nothing in what she has learned to suggest there is anything dangerous about singing to a daemon. There is no shortage of legends and old madre's tales about spirits and monsters that are variously soothed, repelled, or aroused by song. Witch women in the ocean who sing to hypnotize sailors; a tale of an oracle of the god the Imperials call Stromfels who stole the voice of a young duchess, for envy of her singing talent.

On the other hand, if this woman has a daemon indeed, any amount of cooperation with her whims might be playing into a scheme of one kind or another. Unless that's what it wants you to think. You're off the grid, here. Wariness seems wise, but you have seen what becomes of hunters of monsters who yield to every cruel pragmatism.
