OCEANUS (greater titan of the sea and water areas)
CLERIC/DRUID: 10th level in each

This greater titan always has a green shimmer around his body. He is able to raise hurricane winds with a motion of his hand and create waves of great force where there is water. All creatures of water of less than divine status must obey his commands, though Poseidon outranks him on the Prime Material Plane since the greater titans were defeated.
