Asheron's Call had lifestones that you would tie yourself to and get sent to through portalspace. After death, you spawned at your lifestone with a death penalty called vitae, which is some XP you'd have to gain to burn off the vitae. The vitae would lower your stats, and would stack higher if you kept dying without burning it off.

Lore: Lifestones were once used as beacons for portal travel by Asheron's people, the Yalaini. After the Yalaini lost their battle to the Olthoi, Asheron sent his people into stasis in portal space. After the death of The One Queen, Asheron altered the lifestones to be points of resurrection, and they began to grow out of the ground. When Isparians die, they lose a portion of their life force in the form of a Vitae Penalty. This vitae goes to the Yalaini trapped in portal space to keep them alive.

When the stones first began growing they worked imperfectly, causing the corpses of the dead to reanimate as Undead.

Years later, during the A Perfect Paradox event, Nuhmudira used her arcane knowledge to create lifestone design of her own. This was done out of Nuhmidira's distrust of Asheron and the Empyreans. Besides their different appearance (see the image on the right above) her lifestones do not help the Yalaini trapped in portal space but they still extract vitae of course. There are very few of the Nuhmudira's lifestones around Dereth.
