The Loss

The first rule of the Loss is that we don’t talk about the Loss.

A condition experienced solely by Elves, often not discussed as it seems a sensitive topic.
Described recently by Dalitar Amakiir  as 'feeling like your heart has been torn out'.
Cause: Unknown
Orrrrrr is it?! Dal's orb's active effect is that it wraps around the world and turns something 'off'. Dal worked out that this is what's severing the Dreaming to the Waking, so potentially caused The Loss. Rain discovered that this spell became active 942 years ago.
Dal's concerns about switching the orb off is that corruption could extend into the Dreaming.
