I'm afraid it's not something that I have personal knowledge of; I'm aware that it has been done, and by Riftwatch, and that sufficient knowledge remains that I believe it could be feasibly repeated. Certainly, I have no reason to think Kostos would have spoken so if he were not an authority on the matter.

Commander Rowntree, likewise, has some history with the Tranquil. He was not here for Mssr Lyov's ritual, but he may be able to make knowledgeable recommendations, and certainly is in a position to aid the effort if it should be made.
