While walking the roads near the River Chionthar, you see a male elf up ahead on the road.

"Hurry, I've got one of those brain things cornered." he shouts, gesturing behind him. You tense, he must mean an Intellect Devourer.

"There, in the grass. You can kill it like you killed the others, can't you?"

You step forward, looking in the same direction when the elf suddenly puts a dagger to your throat from behind. "I saw you on that Illithid ship, didn't I? You're one of them, aren't you?"
