As usual, I didn't do things the way I should have. First, I captured the Castle of Kaishino, then I surrounded the center, freeing Ciel. Then I took the flag from the Bronnik. And finally, I reached the council, which told me that I needed to take the sword from Kaishino (after the battle with him, it turned out that the sword was buried somewhere, but there was no need to dive anywhere). Then the council told me that Ciel was in captivity (but she had been wandering around with me for a long time), and I needed to take a ring to become the pirate king (with whom I had been scaring the locals for a long time).
In the end, only the island in the upper left corner remained, and it was unclear how to get there.
Where is the sunken Temple, and where is the sword of the pirate king? Please tell me how to get to the island from which Chaos shines.

I found it. It turns out the sunken Temple is the one from which we started our journey. I returned there. I went straight to the exit, not wasting time on battles, because the subsequent maps showed that I needed to hurry.
Returning there, the entrance was open on the left side. We go through it, and in front of us is a passage up the stairs. This is the exit to the surface, to the Castle of Kaishino (lower left corner). Miraculously, this descent can then be used further. Before that, it was only one-way for me. We go down this descent, go further, and there, in the center, is our sword.
After that, there will be a dialogue. Here, you need to save Ciel, who has been running around doing nothing for a long time. Further in the dialogue, they will talk about the sacred seeds. I took the seeds with the mage, and Hak had one of the seeds, so it doesn't matter who collects them. Therefore, during the dialogue, this task will be completed. You need to close 3 elemental streams. However, the location of the streams and the path to the volcano have not yet been revealed.
The elemental stream is located in the same place as the hiring of elementals. From the west, we enter the volcanic lands. There we kill all three guardians of the stream. And the finale is Khimiko. To say that it was an easy battle would be an understatement. Then there is the farewell of the heroes and the end.
