Would it be possible to allow teleporting to the Erebus from any dimension other than the overworld? I would like to allow the player to teleport from the end to the Erebus for modpack story purposes.

This is the line relevant to this question:

Thank you!

Sure, this should be a very easy tweak. I'll look in to it for you.
