In the end I didn't need a
wraithchild tracking device, Uner has been employed by a
master of evil.
In the absence of a minion of my own, I've decided to take up the family trade of being a servant of evil. :D
My
new employer wants me to create a giant "SHINY" magnet, because he wants "all the SHINIES in all of arda".
Perhaps I can encourage the megalomaniacal tendencies later, but first I'll need some elf blood.... UNER!!!
