Category:Last Of Their Kind
From Unofficial Handbook of the Virtue Universe
A character who is a species unto themselves, the only survivor of some calamity that has wiped out their entire civilization. If this civilization used to be important in the power balance between civilizations that still remain, it's now considered missing.
This might mean that they're the last survivor of a particular society or secret order, but for full effect they are actually the last of an entire civilization, or even biological species.
This category can apply equally to heroes and villains and does not just cover biological species. It can also cover kingdoms, empires, clans, street gangs or any other 'group' that the character was once considered part of but has now been lost.
