Honestly give me a world with wildly different dragon types. Give me small rainforest dragons that live in the canopies, hoping from branch to branch, eating large insects. Give me long legged dragons that run on the plains, that hunt in packs. Give me gigantic dragons that are more wing than body and spend most of their lives soaring through the stratosphere. Give me hulking giants that lurk around volcanoes, guarding their territory with earth rumbling growls and breaths. Give me mountain dragons that use the winds around the mountain to glide and fly, looking for prey.
