If the Gralhunds are still active in the Grand Game, one of their agents, Chirada, may be keeping Yellowspire under observation from a small apartment across the street. (See “A Missive from Castle Ward” in Area G12 of the Gralhund Villa.) Alternatively, following Chirada’s advice, the Gralhunds may be mounting an expedition to raid Yellowspire, access the teleportal, and try to find the Second Eye.
