Tethtoril

Tethtoril is a monk in Candlekeep.

If you speak to him before speaking to Elvenhair, he will tell you to go and see Gorion , then he will walk away.

If you speak to him after speaking to Elvenhair he will give you Elvenhair's Identify scroll.

Like Gorion, if you try to attack Tethtoril, he will immediately fire a fatal spell at you.
