Darth Tennacus
Reanimator

Loyalty was as important as it was dangerous. One may be willing to die under the concept of loyalty, or one may die from being blinded by it. Sometimes, the risk was worth the cause. It had always been that way for the Sith, right back to the lineage of Bane. The only difference was that they knew the risk and willed themselves to serve it, nonetheless. A Master may take on an Apprentice; an Apprentice may usurp the Master. Fundamental aspects, many believed, from which the Sith bloomed into an unforgettable shadow which stretched the Galaxy. That the Light may at times brighten is foreseeable. But as long as the Sith's loyalty to their cause remains unchanged, their shadow would shall never waiver.
And so it appeared such loyalty was noticed.
Darth Tennacus came before the great rising Throne of the Sith calmly. He quickly fell into its shadow, his long grey coat buttoned, and its hue inevitably swallowed into the dark. But the Dark Lord of the Sith who reigned above him held an aura ever darker. The Dark Side of the Force embraced him powerfully, but as much was to be expected in the presence of the Maw's crown. Tennacus descended upon a knee, bowing his head in silence, save for what breaths escaped with mechanical emphasis through the filters of his respirator. Once his gesture of loyalty had been initiated, the Sith rose his head but remained knelt. There was a brief pause of which they both stared, until at last the Sith said,
"My Lord."
