This is actually a pretty good suggestion, probably in the upper like 10% of suggestions (although I don’t buy the reason for it being a troll at all). However I have two major problems with it:
A) that escape scene, dimension door is absolutely not enough to fit the escape (as are well, just about every spell it’s a very hard thing to fit, the most popular guess only barely kinda explains it and those that do have good explanations also have a lot of very major flaws).
B) the circus scene doesn’t quite make sense for me. The monster in the the darkness is doing absolutely nothing, whatever is explaining this scene has to be passive and the alternate form ability doesn’t really seem to be passive.
