Editing Periodic Table of Dragons (section)

==Iridium 77==
Iridium dragons are a very rare and poorly understood species. Evidence suggests that they may be among the oldest Metallic species, originating far from their current habitats or even (as some speculate) this world. Some great catastrophe decimated the Iridium population in ages past, the stones recording a thin layer of Iridium scales powdered and scattered across the world. Whatever this catastrophe was — whether it was genocide, divine retribution or a freak natural disaster — the species has yet to recover from this near total devastation. 

The Iridium dragons persist in small isolated enclaves, widely shunned by other Metallic species. Their scales shine with a dull metallic hue, and their weight leaves deep impressions in the ground as they walk. They do not fly, but with their tremendous strength and density can tunnel through rock like a man swimming through water. Volcanoes are often their homes, though the [[#Tungsten_74|Tungsten]] dragons' usual tolerance does not extend to them and are a source of frequent conflict. The Iridium dragons are remarkably resilient, being nearly immune to corrosion and able to withstand huge heat and impact. 

Certain fragmentary writings suggest that a large portion of this near-extinct race did not in fact die out, but may have instead taken refuge at unfathomable depths beneath the surface of the land. The writings are unclear as to why so many Iridiums undertook this self-imposed exile, but they hint that they were not the only dragon race to retreat so far below the surface, and that they may simply be awaiting more "favorable" conditions on the surface. The author's sanity is somewhat dubious, however, and the few Iridium dragons questioned on this matter claim ignorance. 

It is widely whispered in draconic circles that Iridiums are embarking on grand projects, far in the wilderness or deep underground where none can see, trying to return to their old world or finish their "previous work". Whatever the truth of the matter, the rumors of grand Iridium conspiracies have inspired no small amount of paranoia amongst the draconic races.
