Mm... yes and no. There is one person I know from home who I suspect does not come from the same world, but it isn't something I've ever asked him about.

[It hardly matters when Aether is so helpful and when such a question might be upsetting... but Aether smells different, just like this man here does.]

But since I've been here it's become something of a regular occurrence. Many people here come from different worlds, with being here the thing that we all share in common.
