Im actually thinking that Elidibus's plans could unravel if Lahabrea actually returns. If he does something assuming Lahabrea is gone and then the other Ascian turns up to throw a wrench in the works and throw into question of Elidibus's goals with the other Ascians. Its always a bit more fun when there is a multidirectional struggle cause then twists can come out of no where. I will say it is generally Lahabrea that Hydaelyn seems to warn us about the most. I don't remember her ever really saying anything about Elidibus.

Im actually wondering if the big 'forget' that happened during the last calamity will become significant. Its interesting that its specifically the WoL who everyone suddenly forgets. The Tales of the Calamity seem to suggest that for some their presence at the Battle was even wiped when Merlwyb's second in command cant even remember her order to cover the retreat.
