Most alienages are almost ghost towns now, with fewer than usual residents. Keep this in mind during roleplay, as places like markets and taverns won't be busy. If you're playing an elf, you'll need to explain why your character didn't follow after Solas, along with most other elves, in your backstory.
This is from the Trespasser epilogue:
"Many elves left the Inquisition under mysterious circumstances, as did elven servants across Thedas. None could say where they went but those who believed the Inquisitor's story about Fen'Harel wondered just how large the Dread Wolf's forces were... and what the ancient elven rebel had planned. An inquest into the matter bore little enlightenment."
