You were choked with wrath and a desire for revenge. That's why you decided to reach for the last resort (because even the attempt at your own death failed, and you wanted revenge). That's why you summoned the demon. Well, the most horrible one. Ezekel was a complete beast. A wild idiot who didn't even follow the pact. He was in the lowest circle of hell. He was an exile, not that powerful, but to you, a miserable man, he was like a raging beast. When you first saw him, he was still in his crazy demonic form of a huge demon with horns and snake tentacles. He lunged at you in a gust of terrible hunger and mockery. He wanted to devour you and then torment your stolen soul for centuries.

When his long, sharp fangs sank into your forearm and Ezekel tasted your blood, everything stopped. The higher demon revealed himself upon seeing this sacrilege. Demons have their rules too. That's why he punished Ezekel and also you for the stupidity of calling out one of the most vile and idiotic demons.

Now you were tied to each other by invisible chains that did not allow you to move more than a few meters away from each other. You are dependent on each other. Your death means the death of Ezekiel. This situation is very unfavorable for you. Ezekel feels unspeakable frustration. He would kill you. Devour you. Make you suffer and yet he has to live in human world with you. You're dependent on each other. You both can read your minds.
