I`d like to contribute on the history of the two remaining countries:(just suggestions, delete if no)

Lyzor- A desert in the middle of Valios, it is home to the nomadic mamkutes who escaped before the mamkutes of Valios were granted freedom. Despite the freedom granted to the mamkutes, these stragglers do not hold trust in humans, preferring to stay in their desert home.

Oruma- An archipelago of small islands, Oruma is known for it`s developed trade. Oruman merchants are often seen in big cities, selling their rare wares to the citizens of various countries. Oruma is home to the Silver Navy, a vigilante fleet of over fifty ships, patrolling the seas for pirates.
