Listen to the ancient Kromtus spirit 0/1 (Thuliasaur Island)
Spawn is just a bit south of west of Historian. If he's not up, go back and hail the Historian again... when multiple toons are doing it, you may well have to spawn him a separate time for each toon (I did today with some alts today anyway; don't remember what happened the first time I did it, long ago).
