Keep pushing the box. No matter what happens. If you hesitate, they’ll definitely catch you.
Well, that’s not the least bit reassuring, but you don’t see another option. You keep pushing. Your vision gets blurry and your head starts pounding and your limbs ache and it feels like the box has suddenly gotten a lot heavier, but you keep pushing anyways. As the saying goes, the show must go on.
Suddenly, you’re not on the roof. You don’t know where you are. What you do know is there’s what looks like a huge strangely-colored mountain floating upside-down, and a lot of quicksilver in what seems to be a canyon down below. You have no idea what you’re standing on and resolve not to think about it further.
The mountain suddenly takes the form of a bird, and stares at you intensely.
Are you responsible for this? it thinks at you loudly. You think that’s what it’s doing, anyways.
“No. Um, I’m trying to fix it, but it might have gotten a bit big for me.”
The quicksilver is no danger to me, merely inconvenience. But it is able to use the link to your world. I would advise you to seek a way to break the link. This would also hopefully keep out further inconvenient visistors.
“Sounds good, and also something better done by a wizard,” you agree.
You do not have the capacity for magic? The bird seems puzzled. Then how could you suppress the ethereal boundary long enough to traverse the gateway with it?
“No clue. I’ll have to ask a wizard about that,” you shrug. “If I can get back.”
It is not safe for you here, and risks creating worse problems on this side, the bird replies. Unfortunately, as you are not composed of ether, I only know one way to send you back.
By separating your spirit from your body, then pulling the body after your spirit is outside
By shrinking you so much, your mass is not hard to get through the seam, but this is very risky for your body
Having someone from the other side yank you out
Training you in some basic astral projection
Temporarily turning your body into ether, since you’re not able to use magic you won’t be able to control yourself, or know how to get back into a physical state, but maybe someone else can help with that
