I can't say for absolute certain, but Kathul was etched into a ring associated with her - with a compartment that likely had some of her son's hair in it. ( could have been her husband's instead, but Wrathion's response makes her think that she would want nothing to do with him. ) That's pretty heavy evidence she has some strong association with the place so you're most likely right about the bowing.

There's plenty in the group that wants to undo what she's done. Doubt they would mind the routing that way even if it means interacting with unsavory types. But I know the ultimate goal here for most is the beacons.
