Everything in the room was connected to Maia, including the pool. Her roots naturally covered a magma vent and depending on how thin she made it, she could increase or decrease the temperature of the pool.
So in the event that she wanted to increase the temperature, it was as simple as a thought to her.
The water was boiling as the natural energy and heat from the magma surged in, causing the water to bubble even harder.
Laz's body, which had been tempered before, now experienced a pain on a scale he never felt before. While his body was racked with the feeling of being boiled alive, he held on and held it in, never once making a sound. Instead, he let the burning energy circulate through the channels of his body, more than just a little grateful that he had taken the time in the past to strengthen and fix those channels with the help of his black flame.
