Editing Periodic Table of Dragons (section)

==Terbium 65==
Terbium dragons, though very rare and of a similar silvery color as many other Metallics, are immediately recognizable even by those not particularly talented at distinguishing the draconic races because of a unique physical characteristic: all Terbium dragons are two-headed. Terbium dragons have a bulky body, and are only capable of limited flight despite their large and powerful wings because of how heavy they are. The pair of necks that emerge from the shoulders of a Terbium dragon's torso are long but also muscular; the flexible necks grant both heads a wide range of movement.

The strong, muscular build of a Terbium dragon, coupled with their relatively hard scales and low electrical and thermal conductivity means that Terbium dragons are tough. Coupled with their above-average defensive strength, Terbium dragons also boast a good offense. A Terbium's tail is covered in sharp, serrated ridges along the top and sides, and their heavy weight and strong muscles mean that being struck by the tail-swing of a Terbium is akin to having a boulder covered in knives thrown at you. Of course, you can't neglect the twin breath weapon of the two-headed dragon either. Rather than a flame or gas like most dragons, the breath weapon of a Terbium dragon takes the form of a beam, similar to those of Francium or Radium dragons, though green in color and (thankfully) less powerful. However, while a Terbium dragon's breath weapon is not as strong as that of other, more energetic Radiant dragons, it should not be forgotten that the target of a Terbium dragon's ire is rarely receiving just one breath weapon attack. For the poor soul that must contend with an angry pair of Terbiums, the best course of action, aside from fleeing, is the use of corrosive acids or powerful magic which Terbium dragons have no particular resistance against.

Fortunately, Terbiums are not exceptionally violent dragons. Though hardly pacifists, Terbium dragons are quite social and usually prefer civil interaction over violent fighting. Delex-An and Melse-An, the so-called "Bloody Twins" currently employed by the cities of the Jungle Thorn Alliance for their war efforts, are notable exceptions that are viewed with some amount of disdain by the few other known Terbium dragons. Some scholars speculate that Terbium dragons are social with other dragons and even mortal races because each one is two distinct individuals, supposing that living so closely with their twin forces Terbium dragons to learn to get along with others. Whether or not this is really the case is hard to say because Terbium dragons are hard to find and there has never been a "lone" Terbium dragon to compare against.

Though the two heads of a Terbium dragon each represent a different mind with different interests and beliefs, most Terbiums regard their twin with great fondness. Of course, Terbium dragons that cannot learn to get along with their "better half" (as many Terbiums refer to their twin) would presumably live a short life, so perhaps the trait is more a product of nurture rather than nature. Regardless, the fact of the matter is that all known Terbium dragons consider their twin as their closest friend rather than as a sibling. A strange peculiarity worth noting is that one of the few social creatures a pair of Terbium twins has trouble getting along with is another Terbium dragon. Though the draconian twins may surround themselves with the company of others, the only time two (or rather, four) Terbium dragons will come together is for the rare event of mating, which according to Terbium dragons is a very cut-and-dry process.
