Threading:

  Armor/Weapons/Shields/Thrown Holders/Projectiles -
Some items need to be powered by the essence of a Gifted One.

This is accomplished by the Gifted One tying a thread of themselves
onto the item.  Such threading is instantaneous, painless, and permanent.
Threadable items will show up as such on examining them, as will who they
are threaded to, once they've been threaded. Until an item is threaded,
it will be unable to be autoloaded onto a player as it cannot survive
Armagg-odhin's apocalypse.

Threadable items can be picked up, dropped, given to others, stored both
in castles and in rentrooms, etc, even if unthreaded. However, after a
Gifted One threads it, only that Gifted One can use the item.

A Gifted One may loan a piece of threaded equipment.  Unless they
retrieve that item before Armagg-Odhin arrives, or the item is stored
safely away from him, it will be destroyed.
