If you're traveling on the routes when the event starts, you're in a bit of a bad situation! Your character will probably face heightened swarm activity, particularly at night, but this is all entirely up to player discretion; if you want them to miraculously make it through without any problems, then that's fine with us. But there'll be reports of ghost swarms, and your character will still have to deal with the bad weather and a general lingering sense of foreboding.

As for the coma patient, they're unfortunately knocked out where they fall, the same as they would be during a canon update! If a player character wants to take them in to the Center, they can, but otherwise the coma'd character will not be moved, no.
