'I, Sana, immortal of the Celestial Realm, bind my fate to that of Deon. May our souls remain linked until the end of cycles.'"
The dark silhouette spoke these words in a resonant voice. Each syllable vibrated through the air, filled with ancient power.
Deon hesitated for a moment before repeating the same phrase. The instant he finished, two lights—one golden, the other crimson—burst from their bodies and intertwined.
An intense heat flooded through Deon. He felt his consciousness shake, his mind twisting under pressure. Blurry images from another time invaded his thoughts: endless landscapes, celestial battles, and creatures that even gods would fear.
"Argh! What is this!?" he screamed, clutching his head.
"Endure it! The soul link can only be broken by death. If you fail, we'll both disappear!" shouted Sana, her voice echoing directly in his mind.
