Phantom Knight

When a warrior wants to insure a better afterlife for the dead, then they usually find the lost order of the Phantom knights. In this forgotten knight order the adventurers will train their bodies and soul, for their chosen duty. After several months, the warrior will be ready to join the order as one of their knights, but before they become an official phantom knight, they must part take in a ritual. As a part of this ritual, the cadetnet will be put in a trans state. In this state, their soul will be transported to an unknown plain of existence, in this place they will find huge god-like entities. These are the Kings of the forgotten order of the Phantom knights. These entities give the powers of the Phantom knights. After a pact is made between the cadetnet and one of the kings, the adventurer will awake in our plain of existence. After he/she has awakened, his/her body has gone through a transformation, they are an official Phantom knight from now on.

If you are in the same plane of existence as your marked creature, its soul will be imprisoned in your lantern when it dies.  When you are not in combat you can summon a soul from the lantern, there can be only one soul summoned at a time, and the summon is ended when you want to end it, or when you became incapacitated. When you summoned a soul you and your companions can interact with it, but after the summon has ended, the summoned soul will be sent to the Phantom Knights king, thus it can’t be summoned again.
