Ursula Monkton/ Skarthach of the Keep Timeline & Summary

When the opal miner kills himself, something is triggered that awakens Skarthach of the Keep.
She tries to make people happy by giving them money, or even just dreams of money—but it all backfires in horrible ways.
Lettie tries to bind her, but not before she's able to create a portal in the boy's foot and heart.
The boy tries to pull her out of his foot when she's in the form of a worm, but doesn't get all of her.
She recreates herself in the image of Ursula Monkton, tidy boarder and childcare provider.
She threatens the boy, seduces his father, and then causes him to try and kill the boy.
Lettie gives her another chance to use the portal to go home. When Ursula tries to use the portal even though it will cause the boy's death, Lettie summons the hunger birds, which finish her off for good.
