While within the water, there were millions of different kinds of unusual sea beasts and with most of the Lower Plains being covered in uncharted seas, traversing the sea was one of the most dangerous things a person could do.
Along with the sea beasts and multitude of unknown and dangerous creatures that could be found within the sea, there were also powerful storms that were powerful enough to destroy countries and there were innumerable dangers that they may come across.
