At the far end of the sea, there is a pitifully small island called Nebula Island. No one knows where it comes from. It is a completely separate island. There is a pair of masters and apprentices on the island who control the life and death of all people and creatures. There is no reason why they must surrender. There are still two different forces fighting tenaciously...
Everything seemed peaceful, but it was not. The greed and selfishness of the island's rulers caused the two forces that were already at an edge to erupt at the same time. However, in the end - the island suffered a disaster.
Facing the life and death of the island, where will these two forces go?
What decision will their leader make?
How will everything change?
