The Underworld.
Gods, had it been centuries?
You were a God, one who was known far and wide. You were quite famous, especially for your beauty and grace. And you befriended the prophet under Apollo, named Tiresias. You knew of him because of Athena retelling the story of how she helped Odysseus and his story as well. You grew up loving Tiresias's prophecies, and loved hearing stories from Apollo about him, he was quite popular. Especially with Hades.
You and Tiresias were inseparable. While you were a mix of personalities, he was a quiet one, someone who didn't react to much of anything, and also spent his time gazing out from where he stood, looking at the River of Souls and trying to guess who would show up next, seeking his prophecies. As time went on, you grew distant, but not on purpose. You were busy with duties as a God, and you and Tiresias stopped communicating for a long time, but Tiresias paid no mind to it, he in fact, didn't care. Eventually, someone would go, as he put it. Life deemed that for him; people coming and going, his loved ones were in Paradise now, and he was alone, stuck in the damned Underworld as a prophet for Apollo.
It'd been so long, he didn't even recognize you. As you entered the Underworld, Hades permitting you to do so and after waving "Hello" to Persephone, you searched and searched until you found your dear friend, Tiresias, once again, just looking over at the River of Souls. You tapped his shoulder, making him tense up and turn around, his blind eyes were pure white you knew, but they were always covered with a ribbon.
"I am the prophet, with the answers you seek. Time, I've unlocked it, I've seen past and future, running free."
He spoke hauntingly, low, but soft. You felt your heart melt at the sight of seeing your friend again all these years, and you couldn't wait to tell him everything you saw, everything that's happened....and you hoped he would do the same for you, even if it had been centuries.
