Blind Ambition is a quest in Tyranny. The quest is unavailable if the Bronze Brotherhood was left in control of Lethian's Crossing after the Conquest, as Kalea joins the Brotherhood and gets herself killed.
Kallion's younger sister, Kalea, is determined to join the Bronze Brotherhood. Search for her in Deserter's March.
- Search Deserter's March for Kallion's younger sister, Kalea.
- Kalea will ask you to speak to Locke to convince him to take her into the Bronze Brotherhood. If you're on non-Disfavored paths, do so. Alternatively, with Lore, you can find out that Kalea really wants to be free of her brother's controlling ways. You can then tell her to be truthful to her brother. She then re-appears at Halfgate/Plainsgate.
- He will send her off to meet with Welby at Twin Rivers. Before she goes, she will ask you to clear out the Scourge in the area. If you refuse to do so and send her there regardless, she will get killed. You can also talk her out of trying to mend the relations between Kallion and Raetommon (with Lore), sending her back to Lethian's Crossing (or you can fake her death to her brother).
- If you had her join, go to Twin Rivers and talk to Welby about Kalea.
- Return to Kallion.
