Karv

Karv is a Lieutenant of Lockhart, who appears to be a large Orc wearing a gem on his forehead. In reality, however, Karv is the gem, or rather the centuries-old warrior spirit dwelling within it, and the Orc is merely a means of conveyance, with no control over its own body. It is unknown as to whether Karv exclusively uses Orc bodies due to only being compatible with them (presumably due to having been an Orc in life), or whether they're merely convenient sources of raw muscle power. Karv's ancient soul is also the closest thing to a friend the controlling and emotionally distant Lockhart has.
Lockhart tends to recruit "second tier" Orcs to become Karvs - those who have peaked in their careers and are often overshadowed. He tends to emphasize the "you will gain great power" aspect and play down the "you will be trapped in your body with no control until you die" part. Though the degree of autonomy is still somewhat unclear - it is possible that the many orcs subsumed through the ages form a collective with some kind of input and awareness long after their bodies have died, though even if that is the case, the original Karv spirit is clearly dominant.
Karv fights with three large magical swords, although these keep having to be reforged due to the massive strength with which he attacks. The real power is in the handles, so reforging the cursed iron blades is not as large an undertaking as reforging a normal magic weapon would be.
Karv saves his three smaller swords for really dangerous opponents, such as rival Lieutenants. They have the power of an immovable rod, so he can use them to anchor the blades in place - preferably inside an enemy, sticking one dagger in the front and one in the back, so as to prevent them from moving without having their innards shredded.
==Trivia==
*The current bearer of the Karv gemstone is one of only two Orcs yet seen to have facial hair.
