That's the first thing you hear before you fall asleep and awake in Wonderland. But it's a warning from the Resistance. They'll come for you eventually, it's only a matter of time.
In this realm, Wonderland is not friendly and filled with nonsense. It is an evil organization bent on taking you away and ripping something from you.
But don't you fret, for the Resistance is hellbent on taking Wonderland down and setting you all free.
