Cisco had honestly meant to travel to one of the worlds Harry and he had discussed. But as he pushed himself up and looked around, he knew for certain he’d miscalculated and landed on a world he knew nothing about.
And from the looks of it, it wasn’t the sort of time period he thought he’d do well in.
So Cisco accidentally vibes himself onto a different world because after getting Barry back, after getting him out of prison and after all of the other crap they’ve gone through, Cisco decides he NEEDS a break, so he talks to Harry and they come up with a list of possible worlds he could visit and be relatively safe on. Only he messes up by accident and sends himself to a world that is all medieval and magic based.
But before he can vibe himself away, he gets hurt by a passing group of soldiers, and he’s rescued by half Dragon Mick Rory and his human archer lover Oliver Queen.
Who are on their way to mount a rescue of Mick’s dragon brethren, Leonard who was captured trying to save his True Love, Barry Allen, who’s been cursed by the evil Sorcerer Eobard Thawne.
