There's nothing wrong with despairing events, but going specifically after the Sworn seems like a bad idea, especially because you know there are people playing that role after you had Anelia abandon it. You're effectively forcing every one of them to choose a side, and they're not compatible with each other at all.
It's also true that, in a world made up of heroic-figures waiting to play heroes, it's going to be immensely difficult to stop someone who doesn't see this thread on the RPC from wanting to help. If you've got a visible bad guy, expect them to get attacked. It can create some very difficult-to-manage ugliness, and while you're inviting people to contact you and get involved, it still sounds a bit like "But me and mine are the main characters, so we'll be saving the day."
There's also the unfortunate implications that come from all three nations being utterly unable to protect their borders and requiring adventurers to have to save them. Part of what made the former bomb incident work was because there really were Immortal Flame roleplayers on the front line, working to help and doing their jobs. This is going to render the Grand Companies AND the cities' respective law enforcement all completely inept until your FC saves the day (across the entire Alliance, no less).
I admit there's a lot of grumpy-sounding assumption in this post. There's just a lot of scope here and I'm not sure if you're truly wanting to risk alienating Anelia and your entire FC over this. It's usually a poor idea to write yourself in as the savior of entire countries and/or holidays and expect other people to believe you, hence folks mentioning this might work best as an in-FC story with maybe one or two outsiders, instead of it being an open-world event everyone else gets to watch you win or lose.
I don't want you to spill all the details for your event here, but I'm taking "he knows Anelia would get angry if he attacked the Sworn" to mean that this entire incident is over Anelia and your bad guy. It's hard to find folks interested in RPing savior-worship.
