"Just... generally?" Dorian's knowledge of the Dalish didn't extend to most of their gods. A few, certainly, from following the Inquisitor through several Dalish ruins, but not all.
It was safer to stay general, anyway - there were only a few people who'd been topics of conversation. Anders was here, he'd already assured her Varric was as safe as he was likely to get... and that left Hawke. Who was almost certainly too dead to be helped by prayer. Dead or worse: locked in endless combat with an unkillable original Nightmare. But that was hardly something to be flippant about when the only ones present from his own world had been the woman's dear friend and oh yes her lover as well. "For what it's worth, our would-be god met a very final end thanks to the Inquisitor. No one will be threatened by any power of his again."
