Sin of the Past - Illydia's quest | Companions quests Sword Coast Legends Guide
Last update: 11 May 2016
While in the encampment, talk to Illydia. After a short conversation, go to Dalanir and ask him about Lady Zinnsianna. Dalanir only has some information on that and, which is the most important thing, you learn the whereabouts of that character. Go, therefore, to the nearest encampment exit and set your destination to Shrine at Und'ok. After you get there, follow corridors of the cave to find Lady Zinsianna. After a short conversation with her, you learn that Cerric - Illydia's childhood friend is being controlled by Zinsianna. This is why, during the battle, you should focus all of your forces on Lady Zinnsianna. This way, Cerric will remain alive. Before you escort Cerrica to the exit, loot the chest, where you find a legendary one-handed sword. After the escorting mission, Cerric thanks you for your help and the quest ends.
For completing the quest, you will be rewarded with 2000 experience points.
Note! This quest becomes available AFTER you complete the Lair of Rhylfang/Into Eternal Night main quest.
