Designed to contain the “Burning Man;” a sentient being composed of humanoid flame that increases in intelligence with size. It has the capability to duplicate itself, speak and mimic external behaviours. The creature’s two primary goals are to acquire larger sources of fuel and to spread - thus classifying it as a Euclid/Potential Keter within the SCP Database.
It was quite a lot of fun designing a space that could control such a being, particularly in researching the materials necessary hold it. The design I settled upon was practical - purely developed for the form to follow its functionalities.
