Now i know why the dragon cursed Cyril. He deliberately put that cursed to hurt Cyril and for him to find the 'cure' to the pain with Chase. The curse is like killing Chase! I think the curse is killing the host (which is Chase) of the the dragons heart, because the dragon think when Chase die he can now easily kill Roel (the elf) and he can now destroy the humanity without the people who sealed him.
