Star
A star—sometimes multiple stars—typically rests at the heart of a planetary system. Stars are massive balls of incandescent plasma that blast their orbiting planetoids with heat. While there are various categorizations of stars, from blue dwarf stars to yellow hypergiants, all stars produce enough heat to pose similar hazards to most adventurers. The surface of a star is so hot that only full immunity to fire allows a creature to survive there. Any creatures or items not immune to fire are instantly and utterly consumed down to the molecular level—only spells such as miracle or wish can bring back such victims.
- Solar Flares: Occasionally, stars let off bursts of intense energy, visible upon their surfaces as flares of roiling plasma. These disturbances have a deadly and immediate effect on things on or near the surfaces of such turbulent stars. The peripheral danger of these flares is the devastating effect they have on unshielded electronic equipment and radio communications. These distortions can be felt millions of miles away from the star, and typically they cause various electronics and radio communications to cease functioning for 6d6×10 minutes.
