Planetary Spirit Gate Keys

Planetary Spirit Gate Keys are Magic Items used by Planetary Spirit Mages to summon Planetary Spirits.

Description
Planetary Spirit Gate Keys are magical keys can be used to summon Planetary Spirits, beings from another dimension that can be used to fight their contractor's opponents, to do chores or just hang around with. There are three different types of Planetary Spirit Gate Keys: the Lead Keys, the Bronze Keys, and the Platinum Keys. The Lead Keys are common keys that can be bought from stores and are used to summon the Moon Spirits, whilst the Bronze Keys are uncommon keys that can sometimes be bought from stores and are used to summon the Dwarf Spirits, whilst the Platinum Keys are rare keys that can be used to summon the Planet Spirits.

It is possible for a Planetary Spirit Mage to summon the Planetary Spirit Queen, who does not have a physical key, but there are certain conditions to do so. The first condition is the ability to summon at least three Spirits at once. The second is that a Platinum Planet Key must be sacrificed to do so. The final condition is that the Mage and the Spirit of the Key must have a high level of trust between them. Whichever Key is sacrificed to summon the Queen will then crumble to pieces, and will henceforth be unusable. As such, the Spirit of the Key will no longer be able to travel the Mage's world. Therefore doing so is considered the very last resort.

It is possible for the sacrificed key to reforge into a new key once again in one year, which will appear at a random location somewhere in the world.
