While they are trying to undo what they have done, the Morrigan captures Colin and imprisons him in Errwood Hall, which her magic restores into a building, which except in moonlight teleports into a lightless magic realm. This sets up the denouement, a pitched battle between the forces of the Morrigan (goblin-like bodachs and wildcat palugs) and Susan's allies (the lios-alfar, the dwarf Uthecar, and man Albanac), both willing and unwilling. Although Colin is rescued, Albanac is killed. When the elves withdraw their support as a lost cause, the Morrigan finally releases the Brollachan, focusing it on Susan to destroy her growing potential as a force for good. It is the other gift from Angharad Goldenhand which saves the day and the Old Magic is set free forever.
