A Resurrection Point

Resurrection Points are places where you can return to the game after you have been killed. There is usually one in each major area.  They are shown on the map with an ResurrectionIcon icon and can be briefly highlighted by clicking on the 'Resurrection' label to the left of the map.

You can activate Resurrection Points by completing their associated quests. You can still use a Resurrection Point that you have not activated but it will give you the Death's Door debuff.

When entering an area that is new to you may wish to prioritize any Resurrection quest. That way if you do run into unforeseen trouble you can at least avoid Death's Door.
