@Prince of Seraphs
Also, thanks for the info.
And out of curiosity, how long will your characters be out for?
Dawn's not unconscious yet, he just doesn't have the capability to do anything that would make a post worthwhile till someone turns their attention to him specifically. Both his and his sister's magical reserves are completely depleted and he's close to passing out. Chances are he'll stay conscious till they get to the surface. Maybe answer a few questions before passing out.
To answer your question though once he passes out probably a day, maybe two. Depends how impatient I am to post with the twins and how long it takes to get to the following day.
