Gravity Garden?
Angor only came here once before. It was when he was pulled inside by Sunders while unconscious and was immediately thrown out when he woke up.
He checked the place again. When the garden was created, it only occupied a small patch of land in Phantom Island. This time, however, Angor noticed that the garden was larger than before. He couldn't see the edge of it.
The sky was clear but without a sun. Angor couldn't find a light source, so he didn't know how the place was so bright as day.
They were standing within the outdoor library. There were desks scattered around the bookshelves with half-written files and quills in ink bottles on them, which meant Sunders often came here.
