They were free to roam around the castle and the surrounding platform, a sturdy structure of hard wood filled with vibrant vegetation and colorful flowers in every direction. Though natural and lush, everything was orderly and neatly maintained. Damian even noticed a mage carefully tending to a specific plant. However, they weren't permitted to enter the inner palace.
But the castle itself wasn't what interested him. A butler led Damian further up one of the massive main branches of the golden tree, to the old research facility. Despite the reduced manpower and funds of the place, researchers were still actively working there, though Damian was assigned to work alone as per his request. The butler briefed him on the facility's details and introduced him to other scholars and mages.
