"Did this idiot think I captured it just so I can kill it specially or something?" Kingsley said in an amused tone as he wiped his right hand with his left
"Damn those scales are hard as f**k…. Had two potential dragon turn into something else and this bastard reduced that to only one" Kingsley complained
This entire space was a 'pen' he built specially to keep the dragons and dragon-related creatures he had captured so far. Kingsley's imagination may have been lacking ever since he arrived on this planet but it didn't mean that he was absolutely dumb. He had created this tesseract for the purpose of keeping the dragons in areas somewhat like their native home.
