God's new home, and a homosexual dragon!

The ruins of Aqumus were oozing with harvestable mana, the place has been like that for thousands of years now! No one truly understood why the place was so rich in mana, but there were plenty of theories and legends about it. The most believable legend was that these ruins used to house the creator of this micro-universe himself, specifically in the very beginning, when Valporovus was created, which was some millenia ago.

It is also believed that the creator sank his own home, and or kingdom into the sea, because he ascended to a new, celestial home that he made for himself! The rich mana quantities were supposedly fractions of air that the creator had breathed before, and the air was so dense that it refused to dissolve over thousands of years now, regardless of the circumstances. Furthermore, once these ruins sank, it is believed that the sea was given air for the fish to breathe in, before that, the sealife was practically non-existent!
