I see teleportation as something that can only be done by the more aetheyrically inclined and only done in close poximity of an aetheryte (that or the person is experienced in the manipulation of aether). Perhaps raubahn couldn't use return due to his restraints? As for the return spell, I think when people die they die unless healed or resurrected by a capable conjurer(if that's possible?) Within an acceptable time range. Using return definitely requires concentration and if we're unconscious we shouldn't be able to cast anything. I think we only return to our home points for purely game play reasons, as a sort of death penalty I suppose.
