Phlogiston
The curious ability to explode Creepers possess has been the subject of much study. The Players have replicated such a feat with TNT, but this would not have been possible if Creepers did not drop gunpowder. Chemists and mob biologists have labored for centuries to find out how Creepers organically create explosives munitions. Attempts to synthetically create gunpowder are underway but remain highly resource-limited and short-sighted. If the power of smaller explosions with virtually no damage but high force was to be harnessed, the Players could potentially revolutionize the field of warfare by explosively firing arrows or other, smaller, projectiles.
Due to wood and carpeting burning exceptionally quickly, firefighters when called often are forced to prevent the fire from spreading to other buildings rather than extinguishing it. Unfortunately, many unscrupulous building owners choose to skimp on fire protection codes and their residents pay the tragic price. After several devastating fires in quick succession across multiple villages, avoiding fire protection protocols are now commonly punishable by property seizure and execution.
