Sorry if the answer to this is staring me in the face.
But currently I am Lost in time and space and my accomplice is in the other worlds.
Due to a card the terror has gone to 10 and a whole lot of monsters are unleashed therefore the Ancient one awakes!
Do we just continue play until we are back in Arkham or....???
Ok. I am devoured because I am lost in time and space... but my friend?????
He can play the final battle as normal. However I do believe there is a AO that devoures you when you are in the Other World when final battle begins (but i'm not sure of this), but that will be written on the AO card anyhow...
I don't know what happened exactly why in your case when the AO awoke, but just in case
Terror level 10
• The monster limit is completely removed from the game. There is no longer any limit on the number of monsters that can rampage through town.
• If it ever increases again (via a mythos card special ability, for example), instead of moving the terror track marker, add one doom token to the Ancient One’s doom track for each point the terror level should have increased.
• If the terror track increases to 10 by some other means (via a mythos card special ability, for example), return all monsters in the outskirts to the cup.
• The Ancient One also awakens if the terror level has reached 10 and there are monsters in play equal to twice the normal monster limit (eg. 16 monsters in a five-player game).

that is what happened... twice the limit, so straight to final battle... i guess the charachter fights the AO from the other worlds... since the AOs are pretty much omnipresent i guess it makes sense that they can be engaged from the other worlds too...
Note that even though you were devoured at the start of battle, your buddy still needs to inflict 2x doom track in hits on the GOO. 1-investigator games require 1x doom track in hits, but this wasn't a 1-investigator game, even though you can't take part in the final combat. My only loss vs Yig came in just this manner. 3-investigators, one devoured for LiTaS, the remaining 2 got 25 hits before kicking the bucket.
