If you talk to Rowena after accepting An Unexpected Proposal, she says:

Rowena: The fabled Azys Lla. I had heard stories, but who would believe such a technological marvel could exist─and floating in the sky at that. Would that my master could see me now.

This dialogue was clearly meant for Ardashir, who says this as you complete the quest:

Ardashir: The fabled Azys Lla. I'd heard stories, but who would believe such a technological marvel could exist, and floating in the sky at that. If only my master could see me now.
