1. In the time of mankind's enslavement, 'the Gaole' was the place where rebellious humans were sent to work at backbreaking mining and hauling tasks. Dragonkind used this as one of their many punishments to discourage rebellion while grievously retaliating against those who supported it anyway. As time passed, the prison grew less and less effective at the former, and so after one particularly large uprising, dragonkind seized the entire living bloodlines of everyone responsible, locked them in the Gaole, then engaged in gruesome magical experimentation -- or just plain fun, at the expense of the humans. When they finished, a process which took several years, not one human was left alive inside, and the Gaole was stained permanently red. Even now, centuries later, the blood has not washed out. The message was clear: you cannot oppose us, and you will suffer if you try.

That was the Scourge of Gaole. Ire saw it as the moment dragonkind crossed the line from dominant beings to unworthy rulers. That is why he betrayed it to humanity.

2. Without needing any information, Ire knows there are only two dragons it could possibly be: Grieve, the Wizard, whose mastery of magic made even ordinary dragons look like fumbling first-year human students, or Mournless, the Necromancer, who was second in magic only to Grieve and was the most knowledgeable dragon on topics of life, death, and the soul. Only those two would have had the knowledge or ability to exist on after death somehow.
