Guivrus carbonei metallinus
Гивр угля металлического, графит
Guivre of metal carbon, graphite

Most guivres of metal carbon are medium-sized guivres with a long serpentine and laterally flattened body. Many individuals are able to change their appearance, for example, transforming their limbs into fins or wings.

Granum seminis looks like a prismatic crystal, inert to all aggressive aqueous solutions (including Aqua Solis).

A relatively common subspecies. Juveniles settle along the shores of salt and fresh water bodies, adults can go inland.

No specific toxin was found, however, the wounds from the teeth of the guivres of metal carbon take a long time to heal and often become infected. Some individuals are capable of breathing out pyrophoric fine dust.

In ancient times, the scales of the guivres were used as a source of graphite, but now their economic value is not great.
