Editing Periodic Table of Dragons (section)

==Polonium 84==
The nickname for the Polonium dragon is "the walking wasteland" and it fits them admirably. Like many of the heavier Metallic dragons, Poloniums have a field of invisible heat but theirs burns so hot that no Polonium can form a den that doesn't become a smoking crater after only a short rest.

But this is not the cause of their nickname. There is some quality about Poloniums, some sickness in their blood which seems to leech out and affect all things around them. Plants wither and rot, animals are still-born or horribly deformed and humans go mad and die in agony when they come in contact with a Polonium or lands they have stayed in for longer than a week. 

By necessity they follow a nomadic lifestyle, something that becomes more difficult the older they get since their powerful wings find it harder and harder to lift their increasingly dense body.

Polonium dragons exhibit a great variety within their species. Some remain excellent flyers throughout their lives, some prove so toxic that even a day's rest ruins their environment. Some are softer then others, some harder. Some burn with an intense azure light which obscures the yellow-black serrations of their hides while others only release a deceptively soft blue glow.

They have no breath weapon; it isn't needed. The fire that constantly licks across their body burns so hot that only the toughest of magics, armor and dragons can resist it for long. However, the greatest weapon in their arsenal is their touch. Some kind of toxin exists on their teeth and claws that takes effect the moment an organism's skin is pierced; there has been no record of any creature surviving the drawn out, torturous events that follow.

For these reasons, killing a Polonium dragon is an act that would catapult one into the realms of the richest and most renowned of heroes. The materials from their bodies are prized for being able to withstand the hottest furnace and will even remain unscathed by a Silver's strongest lighting. (Much to the chagrin of Silvers, Golds and other dragons that rely on electricity for their breath weapons.)

The constant, instinctive need to travel and feed to keep their bodies fueled means these 40-foot monsters have little time for cerebral matters. This, plus the inability of Polonium dragons to interact with most other creatures, results in them being almost as dumb as common lizards due to their constant isolation.

It is only with other Polonium dragons or Fluorine dragons that they get a chance to interact with intelligent beings. These encounters are often cataclysmic, intense and brief as most environments aren't able to withstand the presence of one incredibly destructive dragon charging through it, never mind two. It is fortunate for the Polonium dragons that they are long-lived and are unlikely to become extinct, despite their rare interactions and even rarer offspring. 

Their courtships have never been observed, with only multiple craters containing sputtering blue fire hinting at what occurred.
