Gabriel sighed through his nostrils, his cerulean eyes searching the earth beneath his feet for a solution regarding the awakening of Adacio. He had to wake up a resting spirit before; he was only in charge of relaying them from the human to the spirit world. He brought a hand to run his fingers through his dark locks, frustrated that he couldn't settle on a definite answer.
"Go to the boy," he said. "I believe the key to waking up the demon lord rests in the hands of his own flesh and blood- his son."
He turned to face the sun, which turned a deep blood-orange as it began to sink into the horizon. Stars dappled the velvet sky like little holes in a colorful cloth, and the wind had picked up, becoming cooler in temperature. His wings spread out to his sides, spanning the length of a truck in measurement, and fluttered as he prepared to take off.
"I will personally watch over the grave until you return."
He took something that resembled a key from a satchel tied to his iron girdle. The polished brass sparkled in his palm as he reached to place it over Assaciel's head so that it hung at her neck. It was his own hand brandished instrument- a divine trumpet that elongated and fanned out when placed at the lips for summoning- but in its dormant state where it wasn't being used, it looked almost like a little skeleton key.
"If you ever need aid, you can call for me using this, and I will come to you. Godspeed, Assaciel."
After that being said, he leapt from the cliff they had been standing on and soared into the sun, his wings morphing his silhouette so that he looked like an eagle in the sky.
