Upon invading a vacant mining shaft in a small village, the flabby dragon gained a cult following among the impressionable peasants of the dark ages. They brought her their dead livestock day in and day out, dumping their carcasses into the deep and now abandoned shaft, directly into the fat dragon's waiting maw. They intended to grow her to the point she would be able to single handedly destroy the castle and dethrone the king and gain power for themselves, clearly not correlating feeding with weight gain rather than regular growth. Eventually she grew to such a size that she pressed against the walls of the cramped mine shaft, and no longer being able to fly out, she was transported via strenuous tunneling to her newly built dungeon in the king's castle, the royal finding her to be an ample security guard for his many jewels and riches.

Now, she lays immobile in her dragon's keep, being fed hundreds of meals a day to keep her figure and the king's jewels safe. Her body is long-overcumbered with fat, her flanks swollen and pressing outwards, while her heavy limbs press against her belly shelf, equally fattened. Most noticeably, her once ample wings had shrunken to merely useless flabby stumps. An emblem marks her room, though it was made when she was transported to the chamber, now being long outdated. She roars at the sight of another meal, er body jiggling slightly as she writhed her flabby face in an attempt to reach the meal before it is even offered to her.
