ian set his creations, known by scholars as "the lesser/lower gods" down on the earth and each of these gods in turn created a race for this new world. roha created the humans, gale created the giants, marea the elves, flox created dökkálfar and dark elves, and silva the halflings. the lesser gods placed their creations on separate regions of rohan, but ohn felt this task was too important to be left in the hands of the lesser gods, so ohn created dragons to divide and patrol the regions.
