The sixteenth season of Survivor, took place on Micronesia, Koror and Palau.

That point is in the Philippine Sea, about 530 miles due east of Pollilo Island,

and 600 miles north-northwest of Koror in Palau.

Palau is a tiny country consisting of several hundred islands, lying to the east of the Philippines. Its largest island is Babelthuap (Babeldaob). Other important islands include Koror and Peleliu. In 2006 the seat of government was changed from Koror to Melekeok on Babelthuap. Palau's rock islands are world famous for their natural beauty. For many years Palau belonged to a group of islands governed by the US. Palau is still heavily dependent on US aid.

I have absolutely no idea, but if you are familiar with the region, perhaps you will know which of the addresses found in the link below is the appropriate one to which you can write in order to find out. I hope it helps.

Seems Palau is the name country in the western Pacific Ocean comprising a group of volcanic islands that are part of the Caroline Islands.

Capital: Koror

Then in what way an adjective is sought for the above name Palau?
