A temple with a sphere covered in arcane symbols and surrounded by green light would be great for that!
So I sat down today to draw a map, the first in weeks, and I hope I came somewhat close to what he was looking for. Drawing the symbols on the sphere is pretty difficult, so I threw them on the ground instead. Then I put a weird bubbly pattern on the globe, because bubbly globes are scary enough.
I can see the globe being some sort of transdimensional gate and the chosen people enter the temple and walk straight into it, experiencing some wacked out Doctor Strange weirdness. They come out of the other side 'cleansed' or some nonsense. ;-)
I hope you like it Sean. And everyone have a Happy Easter,
