Echo

Echoes are individuals who have died Outside but now live on in The Hollow, forever severed from their physical body and the real world.
The leaders and prominent citizens of the Hollow tend to be Echoes rather than Wires. Wires must spend time Outside to keep themselves alive, and that time causes them to fall behind Echoes, who may devote all their hours to their pursuits within the Hollow. Echoes also do not need to sleep or eat -- though many still do so out of habit or enjoyment -- giving them yet more time and resources to focus on other pursuits.
