Bronia spent most of her time napping in her cave, only occasionally waking to take a lap in the sky and stretch her body, before resuming her nap. She was a Red Dragon who didn't do much of anything.
Even though she did nothing, her mere existence influenced her surroundings. As a powerful Ancient Red Dragon, the large hills that she had chosen as her nest were constantly rising under her strength, with magma beneath them continuously converging.
In less than ten years, under the influence of Bronia's power, the small hill evolved into an active volcano. During one of Bronia's slumbers, the volcano erupted and continued to do so without interruption.
The searing magma turned its surroundings into a wasteland, the scattered volcanic ash blocked the sunlight, causing a vast death of plants. The already barren hill region became even more desolate.
However, Bronia did not mind, because her selected nest had become even more suitable for her residence.
