Castaway's Journal - Day 0

Strangely enough, the island is shrouded in a thick fog that makes discerning it from the sea impossible.
Attempting to steer away from the fog, I turned rudder, only to be enveloped by an even deeper fog. Just then, someone attacked me!
I have no idea where the attack came from, but my boat was all but destroyed. With nothing but wreckage left, I was still somehow able to make it to the coast.
This island exists in no database. It is an island hidden from the world.
Why is it being hidden? Why isn't it on any maps?
I'm certain this is all intentional. Was that attack on my vessel part of this attempt at complete concealment?
There are more mysteries than I can count, but I am resolved to discover all of this island's secrets.
