Death's Order

When first found it was embedded in Key's back as a pair of tattered mechanical wings, but can take the shape of anything its holder needs

A weapon said to be able to destroy anything

Various different ethereal metals mixed with elements of altered Phantom Jade

Depends on its form

The same time Molhaven was created

Shape shifting, power amplification, power dampening

Isn't found until the end of Infinitalis' storyline, found in the Enderspine
