Eos was silent as Circe began to speak, but his attention was immediately drawn to the first words, speaking about the rain of bones in her dreams.
He had created three powerful Incarnation, one died after creating the Origin Realm not too long ago, another went missing after Eos summoned the power of his Final Form for the first time while using the Incarnation as an intermediary and the the last was devoured by Lumen, the wings of Enoch after it told him the secrets of Existence and the origin of Enoch, the Luminious and the power of End.
When his Incarnation entered the Temple of End and met Lumen, the connection between him and Eos was nearly shielded, similar to what was experienced by his missing Incarnation after he used his Final form, and it was the closest clue he had to his missing Incarnation.
