Astarion's act 2 romance scene WITHOUT meeting Araj the blood merchant

The second, less known variant of Astarion's act 2 romance scene. Requirements: Resolve the deal with Raphael. Witness the scene in Moonrise Towers featuring Ketheric Thorm and goblins. Do NOT talk to Araj the drow merchant with Astarion present in the party. Long rest. (It can take more than one long rest to trigger, sometimes.)
