Uncut Eternite Gem

Uncut iridescent gem found in Lindwurm nest. The Gem has been identified as Eternite, a very rare type of gem originating from the moon Eternity. The facets glimmer with different colours and each time you look away from it you seem to see an image in one of the facets of a place/scene/person. But it is always as you are looking away and the image is at best fleeting, seen out of the corner of your eye.

You have also discovered that Eternite is very useful to crafters. The gem can be set into any simple item and the item genuinely seems to improve the fortunes of the wearer/bearer. You also, more importantly found that it is a necessary component in the construction of any fate-linked item (including maker's keys).
