Kirkwall's Alienage is the Alienage of the elves in Kirkwall. Every night the Kirkwall City Guard closes a great iron gate at the entrance to the Alienage. Yet, despite their poverty, the elves still take comfort in the fact that they are not as bad off as the residents of Darktown.
Kirkwall's alienage is even more dilapidated than the rest of Lowtown, but the elves go to great lengths keeping the place looking bright and festive. The vhenadahl ("Tree of the People") standing in the middle of the alienage is a symbol for elven pride and shared cultural identity, and it is lovingly cared for.
It's difficult to say if the elves would continue confining themselves to the alienage if they were given the chance to mingle. They may not admit it, but some feel that living among their kind is far better than living with humans, no matter how terrible alienage life may be.—From In Pursuit of Knowledge: The Travels of a Chantry Scholar, by Brother Genitivi
