As far as the story itself goes, your dragon is essentially the chosen one whose destiny is to fulfill a prophecy of saving the human race from hordes of strange creatures that are infesting the land. Guided by various NPCs along the way, your objective is every area is to exterminate all of the local monster lairs while defending and constructing towns. If a town is not present in an area destroyed monster lairs will reappear and begin to spawn monsters again, so clearing out an area has to be done within a vague timeframe before lairs start to reappear. Once all lairs are leveled a town can be built, which is done simply by going to the magic town beacon and pressing "B". Every once in a while you will be tasked to kill a powerful monster, which while they do deal and take much more damage than their smaller brethren the same tactics to defeat them apply.​
