NK-3

Inhabits: Myyydril Caverns, Kashyyyk

Star Wars Lore
NK-3 was the designation given to two IG-100 MagnaGuards that operated as the personal bodyguards of the N-K Necrosis droid on Kashyyyk.

The assassin droid IG-72 captured two MagnaGuards on behalf of the scientist Treun Lorn, to be used as part of Nycolai Kinesworthy's research with the remains of General Grievous. The result was N-K Necrosis, a killing machine in the vein of Grievous himself. The NK-3s were used to train the Necrosis droid in the lightsaber forms Grievous had once instructed his guards.
