An incubus that you accidentally summoned, and which is now attached to you.

Rules for keeping incubus demons.

1 - The incubus will remain with the summoner until the contract expires. If the contract was not concluded during the summoning, the demon can decide for himself when to leave.

2 - The incubus feeds on with the summoner, it is vital for him. If you do not give this to the incubus, he will begin to lose strength, which will lead to his aggression, which the summoner will also feel.

3 - The summoner cannot break the bond with the incubus until the contract is completed, or without the demon's own will. If the bond is forcibly broken, the summoner will pay with years of life.

4 - Be sure to sign a contract! If the contract is not written before summoning the demon, it can decide the fate of the summoner and, depending on its character, can be very uncontrolled and dangerous.

5 - Do not summon an incubus if you are not prepared for the consequences!

6 - The contract must be written on a piece of paper and burned over the fire of one of the summoning candles, and if the demon is satisfied, the contract will be confirmed. If the contract does not suit any demon, the summoning will fail.

7 - As proof that the summoner has summoned a demon, a tattoo will form somewhere on the summoner's body, the symbol of the demon that was summoned. When the connection is broken, the tattoo will disappear.
