The heroes bring Paelias' body west to Halvath the Green Regent at the Fiery Spire. On the way they spot giant scouts, but leave them be. Lirael leaves the others at Heartford to lead the Tigerclaw Barbarians to reinforce Orlbar. Halvath now seems rooted in the 'greenhouse' atop the Fiery Spire, channeling Mielikki's power to drive back winter from the Vale. With help from Selune and Shar, Halvath wrests Paelias' soul back from the grip of Orcus. Paelias' amulet has vanished. Then they travel east to Castle DeTrevani, consult with the Baroness Amara, Sir Dolf, and the visiting Lord Boris.

The heroes fly east on spectral steeds to Redar north of Orlbar, where Arya senses that a fell ritual nears completion. The heroes attack the giants, interrupting three Icemasters engaged in a ritual summonings, and cut it short, causing hordes of Chillborn zombies scattered beneath the snow to be stillborn. In a bloody battle 17 giants perish, one fleeing, while Jareth too is killed, though he slays a female Icemaster shaman as they bring him down. Anaveth runs forward and is able to wrest Jareth's soul back before Clenderi can take it, successfully Raising him.
