Splash of the Wilde
In a room that could be described as a sealed barrier room, the Splash of the Wilde is currently there and is being harnessed. It is on top of a three-meter-tall podium and is guarded by five guards inside the room and five guards outside the doors. There is also one mage checking every once in a while, that the divine artifact fragment is operating properly.
The Splash of the Wilde looks like an orb made of water that is continuously flowing in a spherical motion. Not just anyone can use it as it would take years of studying to even harness a fraction of its power if they are not chosen by the Will of the Wilde.
If King Neptune is not greedy then he might have activated the Splash of the Wilde using Kabrakan's help. The leviathans would not have easily damaged the barrier if Kabrakan activated the full might of the divine artifact fragment. They would not have sacrificed many lives of the merfolk, but greed always gets in the way.
