Dal Shabet

The scabbard began to greedily absorb energy, as if a weary traveler was clinging to a bottle of water. This continued for some time, and then something strange happened; it seemed as if there was simply nowhere for the energy to go, and it was about to explode. At that moment, all the followers of the demon of knowledge disconnected, and their minds saw the same vision: a dark dungeon, on the floor in the center of a magic circle lay a black heart, several eyes and other internal organs were scattered on a table, and a pile of bones and flesh was in a bucket nearby. Each of these parts was charged with magical energy, but at some point, it could not withstand such a large amount of it in this state and ignited, including the heart. Mirinoth ran into the room (for everyone else who is not familiar with him, he is just an old man in black robes); he was clearly very unpleasantly surprised and hastily used some kind of spell on the heart. All the other remains burned to ashes. The vision ended.
