Orb of Death

Orb of Death is a magic sphere that enables the user to summon undead creatures.

Description
Native to the New World this item allows the user to summon and supplement the undead. One of the most unique traits about this item, is that it is fully sentient with desires and wishes of its own. Its able to communicate with its user through telepathy using physical contact.

Appearance
Besides its sinister name, its appearance isn't really noteworthy. It mostly resembles a black lump or a plain black pearl, but since its shape is rough is most;y closer to the former. Ainz himself described it to be a bead that one could find of the banks of a river.

Personality
Given its powers and name, the Orb is no doubt a evil creation. It has an obsession over death bordering to worship. Ever since its birth its only wish was to spread death across the world. However despite power over the undead, it does respect those that are superior to it. For example upon seeing Ainz Ooal Gown power, who he declares as the Great King of Death, it swears it fealty to him and requests to join the ranks of the Great Tomb of Nazarick. Its willingness to serve Ainz is akin to the loyalty the NPCs of Nazarick have for him,as he was constantly arguing with his new wielder, Hamsuke to return it to Ainz.

Abilities
The Orb of Death can allow a magic caster to cast multiple necromantic magics in a day. Also it seems to be able to subtly use mind control to manipulate the user through fear.
