Editing Periodic Table of Dragons (section)

==Astatine 85==
Just as Uranium and Plutonium dragons birth Francium dragons once in a great while, so too do Neptuniums give rise to the rare and mysterious Astatines.

Astatines seem to contain intense bottled energy, and live only slightly longer than Franciums.  Unlike the extroverted, angry, and aggressive Franciums, the dark black Astatines are very morose creatures, consumed with their impending mortality.  They eat almost nothing, and seem to shun other creatures almost obsessively. When they can be roused to action they are ferocious fighters with little lasting stamina. Generally this occurs only when their Neptunium parents call them to war against other Metallics, as Astatines have no natural predators.  Only the occasional hungry Lead makes an attempt, and there have been no recorded instances of a successful hunt.

At some point during the brief lifespan of an Astatine dragon (rarely more than a year past its birth) it undergoes a cataclysmic event.  For reasons unknown, theorized to relate to some internal chemical change, the dragon rapidly begins to glow.  Within seconds it has transitioned from a deep black to a intense, painful white.  Nothing is known about the transition after this point: the only known survivor quickly hid more than three hundred yards away, only to return moments later to a blasted, glassy crater wavering with impossible heat.  No trace of the creature could be found; it is thought to have flown away or transitioned to another dimension entirely.

The Astatines can breathe a dark, black-purple gas, which ignites the air around it with a heat so intense it melts some metals merely by exposure to the resulting light. It is also highly corrosive, but few substances suffer the heat long enough to dissolve.
