Meanwhile at Lord Asriel's fortress

Via their lodestone-resonator Chevalier Tialys and Lady Salmakia report to Lord Asriel, although he struggles to understand them at times due to their ancient way of speaking.

At that point Baruch arrives. He is badly injured as he has been attacked by enemy angels en-route. Baruch, his life rapidly seeping away reports that Jopari is sending his son with the subtle knife, but that the boy has decided he must rescue Lyra first and has gone to the caves. With his dying breath Baruch is able to point to the map and reveal the location of the cave.

Lord Asriel instructs Lord Roke to tell Chevalier Tialys and Lady Salmakia to hide in the army’s zeppelins as they travel to the cave and to brief him hourly on the enemy’s plans for attack.
