I mean if we're talking foreshadowing the Syndicate guy back at the Valley of Kings server mentioned a genocide happening in the near future. And since we want Orion and Caly to get out of Hyril'ar and back to the path of the main story then said event could refer to a genocide of the elves with Wyatt possibly initiating it (another foreshadowing to this would be Caly mentioning that she was prophecized to save her people, but there doesn't seem to be any potential threat to the elves at the moment except for Wyatt as he's someone who would be willing to cut down anything that would stand between him and anyone holding the gems, so leaving her realm with Orion would be the means for her to fulfill that prophecy). Lorelei and the General could instead die during the event (along with any other elf that Orion befriends during his stay), giving more reason for Orion to push himself to grow stronger beyond his current limits ('cause as it currently stands he can't even go against Wyatt and I dunno if having the LIs with him would be any improvement) while also giving reason as to why Caly would end up travelling back to Eternum/Kredon instead of being forced to stay in her homeworld and rule*.
*course the other option is she gets exiled or she sneaks off, but I feel like for the latter to occur she'll need a very solid reason for her to do that after trying desperately to get back home following her imprisonment. And no, lusting over Orion's magnum dong is not solid enough reason for that methinks
