Another quick one.
Sergio walked into an empty room with metal walls, closing the door behind him. For a closed off chamber, there was ample oxygen in here. As he surveyed the small room with limited illumination, Sergio noticed the scattered mounds of dust on various corners of the room. As he took a sniff, he was almost overwhelmed by a rather odious stench. The stench was so wretched that Sergio had to resist the urge to vomit.
What Sergio didn’t noticed (or pay attention to) was the slowly but building increase in room temperature. Even when he wiped sweat off his brow, he assumed it was normal for a room of this size and design to get warmer over time. His attitude changed when he spotted the walls glowing a dim orange and slowly getting brighter with each passing second. It was long before he was startled by the suddenly bright amber light emanating from the ceiling. Realizing where he was and before he could react, the light enveloped Sergio, bursting him to flames.
When the light dimmed, Sergio was nowhere to be found. In his place was a smoking mound of fresh dust added to the pile in this small, empty furnace that was still very active.
