Poseidon

 Poseidon is the Estrium God of the sea, earthquakes, storms, and horses.

Being God of the Ocean was never a small responsibility but it was placed upon the right man indeed. Poseidon could be counted on to be the most sensible of the three brothers - level-headed and calm under pressure, he excelled at his role as the middle child. The care of the oceans was bestowed upon him with the greatest honour. The seas could be unpredictable, much like the God himself, and he found over the years that he shared many more similarities with the mistress herself. Great power could be harnessed from her depths, and in the wrong hands this power could do far more damage than good. For a long time, Poseidon was alone with the ocean, and spent most of his time living away from land. The water was home to him.
