Inter-dimensional portal travel isn’t an exact science. You could try going back the way you came but you could just as easily end up in the void between worlds with no hope of returning to any.
Demanding answers and getting angry about it isn’t likely to get you anywhere, regardless. Especially when we’ve all been pulled here from different worlds, and at the time of arrival had important reasons to want to go back to them.
Come April, I’ll have been here two years. So you better get used to this place because you could have a long stay ahead of you.
