Emerald

Jaskier was a dragon that hoarded people. His friendships were his hoard. And Geralt, oblivious to all of this, was the prized piece of it. The one his instincts insisted was his mate.

When Geralt rejected Jaskier on the top of the mountain, Jaskier ran. Finding himself stuck in his dragon form, he flew off in search of another member of his hoard, Ciri.

Little did he know that Ciri was in search of Geralt.
