Passage to Dawn is a 1996 fantasy novel by American writer R. A. Salvatore. It is the fourth and final book of his Legacy of the Drow series. Plot summary Passage to Dawn finds Drizzt and Catti-brie aboard the Sea Sprite six years after the events of the previous novel (Siege of Darkness, 1994), with the company of its captain, Deudermont, its wizard Robillard, and its powerful crew. The Sea Sprite is indeed a feared force on the Sword Coast, with few pirates choosing to attack its deadly wizard, drow ranger, panther, archer or ballista. They have been hunting pirates for the six years after the Battle of Mithral Hall. The balor, Errtu, who needs Drizzt to break his banishment; takes Deudermont's shape and it is unmasked when it hints to a mysterious island. Deudermont looks for the island to find out who sent the creature. The Sea Sprite crew goes to Mintarn in search of information about the mysterious Caerwich. They are attacked by pirates, but they manage to escape also because of the magical arrival of Harkle Harpell, who joins the crew. After a long and perilous journey, the Sea Sprite reaches Caerwich. There more dangers await the companions, but they eventually find an old hag who gives a riddle message to Drizzt and Catti-brie. The drow believes that the message implies that his father is alive and held by Lolth. The companions look for more information from a fiend of the Abyss, contacting it through a priest. On the journey back, the Sea Sprite is nearly destroyed by a storm and is saved by Harkle, whose spell magically transports the damaged schooner in Impresk Lake, near the residence of the priest Cadderly Bonaduce. The companions go to Icewind Dale where Crenshinibon lies, the place where Errtu will more likely show up. In the meantime the crystal shard itself is found and taken by Stumpet Rakingclaw. Errtu is summoned by a wizard, but he breaks free and flies to Icewind Dale. He takes Crenshinibon from Stumpet, capturing her soul and using her body as a bait to lure Drizzt to him. Stumpet's body leads the companions to the Sea of Moving Ice. There they are attacked by Taers sent by Crenshinibon, and they beat the creatures because of the arrival of Revjak and his warriors. Berkthgar and his men, who were also following the companions, arrive as well
