The Glass Dome was an old-world invention, originally designed as a containment box. Over the years, and throughout the course of history, when abilities and Mythic creatures became a norm in everyday life, the glass dome was refined to contain ability users.
To achieve a reinforced structure that even the strongest mutants couldn't break, Mythic Shards were infused into the glass itself.
Sometimes, these domes were designed to contain prisoners, the worst of the worst mutants who sought only to use their abilities for selfish reasons. These domes were the ultimate prison, with no doors to open whatsoever. Other glass domes, like the ones at the Oval Academy, were designed for training purposes and, as such, had doors.
Kinsey walked back into the second-year building and slipped into the fighting room. Drax Tan, far too focused on the fight unfolding inside the dome, failed to notice when she reached the control terminal and pressed a button. Slowly, the dome doors began to open.
