==Ytterbium 70==
Ytterbium dragons, which look nothing like Yttrium dragons despite the similarity in spelling, are a bright silver similar to freshly polished Silver scale, with a white tarnish powder which they take great pains to remove. A Ytterbium dragon with any white on its scales is greatly weakened, perhaps even one of the Inflicted. Ytterbiums are one of the few dragons that become less dangerous when Inflicted, since they are unable to use their scale powder.

Ytterbium dragons are a rather testy species, preferring their own company to anything else, though they will tolerate other races for a short time. If you find yourself in the company of a Ytterbium, it is best to keep your mouth shut and your head down. That being said, if their attention can be avoided they make decent guardians. Some noblemen have even enlisted the services of a Ytterbium in exchange for a place to stay. They will guard seldom-visited vaults or manors as long as they are not bothered by other races too often.

Ytterbiums have a vivid green flame that comes close to a Magnesium's in intensity. In fact, some say that though it is not as bright, it is even hotter. It is not their flame that their opponent should fear, however. The body of a Ytterbium is covered in scales that are perhaps unique among dragonkind. Each scale is sharply curved, giving them the appearance of hematite. Under these scales is a powder that causes intense stinging upon contact with the skin or eyes. The scales can also be flared in a desperate measure, releasing all the powder at once, after which the dragon will ignite it with their flame. Few beings can survive this, as the air instantly becomes hot enough to melt glass. Some Ytterbiums have been known to selectively flare the scales above their mouth, giving their breath additional intensity for short periods.

If using electrical runes against one, it should be done early. The more strain they are under, the higher their resistance to electricity becomes. One that is nearly exhausted has been known to shrug off even a Silver's breath. In fact, if they know they will face a dragon with electric breath, a Ytterbium will sometimes pick a fight with a dragon they know they can beat, then deliberately fight poorly in order to gain this resistance.

For unknown reasons, Cesium dragons value Ytterbium scales for crafting sundials above all other materials and will do anything to get one.
