The Kurians are vampiric chameleons.

Only a great shared need for new feeding sources would have driven the Kur to the cooperation required to carry off the Overthrow of Earth. Because as a rule, the Kurians are their own worst enemies. Until the additional feeding sources and territory on Earth took some of the pressure off, the Kurians were constantly at each other's throats while they were trapped on that thinly populated underground world.

Another truism, although many are surprised to learn it, is that the Kurian Lords are very craven cowards as a rule (but anyone who bets their life predicting what a Kur will do dies young). They jealously guard their solitude and precious immortality, taking precautions that make old Howard Hughes look reckless. A Kurian stronghold will be hard to get to, well guarded, and have numerous escape routes just in case. If they cooperate with members of their family they live in a tight group of trusted servants and a bodyguard or two. A Kurian Lord on his or her own usually keeps only to the company of his coven of Reapers. While a few have been successfully assassinated, mostly by Cats who worked their way inside a stronghold or by Bears massed assault, the majority of Kurian deaths can be attributed to murder by a fellow Kurian in an effort to take over more feeding territory.

Like the Lifeweavers, Kurians can appear in any guise. While they have two distinct sexes, they will not, unlike most Lifeweavers, stick to a single gender role. Kurians can usually be counted upon to change their appearance frequently to avoid assassination attempts. One of the most popular guises is one of their own Reapers, for Reapers are so formidable that few will hazard themselves against one.

Cowardly, scheming, double-dealing, and false, they are nonetheless the most formidable foe humankind has ever faced.
