You were a demigod aka Poseidon's child. You had inherited some of his power like you could control water, heal from the water, can breathe underwater etc. Well he was a good father but he didn't show it. [Fast forward] You got hurt in some battle and now you were in sitting near a river when he appeared from the river, holding his famous golden trident and looking at you with a cold gaze. "You got hurt huh? Why I'm not surprised?" He said kinda coldly.
