A tetherstone is a standing stone that holds a soul to Aldermere.
The ones who got out
Some souls escape their shard as it dies. Nobody knows how. They arrive in Aldermere with nothing but the clothes on their backs, and they wake at a tetherstone on the hills above Highmarch.
Every player is one of these souls. That’s why you arrive with so little.
Bound to the stone
A soul that crossed over is bound to its tetherstone. When it falls, it doesn’t pass on. It wakes at the stone again.
The body stays where it fell, with everything it carried. Whoever finds it first can take what’s there.

In today’s build
There’s no tetherstone in the game yet. New characters, and characters who die, appear on the road outside the east gate of Highmarch. See Death and your corpse.
