Honestly I'm not sure how else you expected him to escape the Warp, given his universe of origin. Honestly speaking, I'm not even sure half a warp whale corpse crashing onto a city is even the most destructive thing he's been involved in.

That being said, if you want to get on Yggdrasil, the multiversal void is breathable(you won't suffocate in it at least) and you could appear outside of it, and if that was the case people would probably move to help Guts get inside.

This plan, for example. I'm not sure how you'd even know Guts was in the whale corpse if it was just floating in space.

But if you really, really insist, I can choose some other place to land.
