My Huion Myth contests entry.
Long ago when earth was fully covered by seas and the land started to rise.
Seafolk created a guardian who was half their own and half man of the land.
The Guardian had a job to watch over the temple where they kept the Heart of the world, a powerful artefact that had unimaginable power.
Time passed and wars raged, cultures and civilizations rise and fall. The memory about the great Guardian was slowly fading.
Legends about him were forgotten... but the guardian kept doing his job.
Now centuries have passed and beacause of spending this time in darkest and deepest part of the sea, he himself have forgotten who he is, who he was, and what is his purpose.
He is not dead, he is not gone, he is the Forgotten Guardian.
