Lethal Devotion

You can only start this quest if you completed 'Partners in a Dangerous Crime' without warning the two lovers. Head back to The Cantori Diamond and speak directly with Chance Candide. He'll tell you about a Venatori ambush that the Crows plan to counter, with Rook's help.

Fast travel to the Heart and Central beacon, located east of The Cantori Diamond. Cross the bridge to the east and make your way towards the Dellamorte Estates.

Upon arrival, you'll find that a fight has already begun. Some Crows will be present and will assist you from a distance, though their contribution is mostly cosmetic. Your main task is to defeat two Elite Venatori Centurions, an Executioner, and two mages. As you fight, you'll overhear the tragic end of Pearl and Sable's doomed romance.

After defeating all the enemies, return to Chance Candide at The Cantori Diamond. He'll comment on the affair and give you your reward: 500 EXP, 200 Gold, 5x Fade-Touched Crystal, and +50 Antivan Crow Strength. This reward is similar to the previous quest, effectively doubling your earnings if you're okay with a tragic outcome.
