Here's a bit of that fiction:
"You feel called to the Search." Olympe stroked her friend's back under Reina's half-furled wing. It wasn't a question - even a sleep-deprived Spiral dragon would be able to tell that Reina grew more and more restless.
"No! No, of course not," Reina lied, tucking her wings back down. "I was, well..." she trailed off, knowing better than to try to convince Olympe, when Reina didn't believe it herself. Olympe wanted Reina close to her almost as much as she wanted Reina to be happy. Almost. But not enough to keep Reina grounded when her heart called her away.
Olympe put a small bundle on the ground in front of Reina. "When you find the right place, put this on the ground, and call on the Gladekeeper." She pressed her cheek to Reina's, breathing in her scent for a long moment, then stumbled away, knowing Reina would understand.
Reina didn't speak, and didn't watch her friend half walk and half fly away, deeper under the tree. Reina did understand. Some farewells are too big, too important, for words. Reina wanted to be close to OIympe, too, almost as much as she wanted to find her Charge. Almost.
Reina cradled the bundle gently, then threw herself into the sky. Only the clouds and wind saw her tears.
