In all truth, Tennacus did not believe that his apprentice would accomplish the task set before him without additional support. Through the wraith he watched silently, his hand stretched over the burial of his apprentice's brother, waiting to use the Force to do it for him. And yet, he felt himself wanting to pull away, returning his arm to the shadowy remainder of his guise. His assistance was not immediately needed. The soil trembled, with granules of grit tumbling over one another as a mountain suspiciously arose beneath the dirt. Tennacus watched through the abyss of his midnight silhouette with focus. The Dark Side had grown strong beneath their feet. The likeness of forgotten bones moved in unnatural disturbance. Skeletal remains ascended. Tennacus finally lowered his arm.
The Dark Side had moved through him. The apprentice had tapped into such disturbed power, raising the ruined remains of his brother from beneath the dirt. His decomposing guise climbed out slowly, until at last it erected itself in full before them. There was strain emanating between itself and his apprentice. Like a rope being pulled on both ends, inevitably ending in one side letting go. For this, Tennacus returned to raise his devil-like fingers through the shadow, assisting in the manipulation of this dark art. Never did he expect his apprentice to animate an empty host by himself on the first attempt. Tennacus had failed and suffered punishments multiple times himself at the hands of his old Master, sometimes even forced to lose focus due to unnecessary torment. The strain eased from his apprentice. The weight of the corpse's animation rested upon both their shoulders.
"I needed to see," the Sith answered. "We needed to see. For millennia, the Sith have fought to ever expand their conquest and knowledge of the Dark Side. But there are many of its secrets long buried within the archives of the past. Forgotten tomes and Holocrons teach us that the ways of the old were ever powerful. Through its teachings, the likes of Force Demons, shadowy hosts, and even the infamous Leviathan, have been conjured up to achieve sufficient success against our foes. They value moral - principle - and it is that which disconnects them from greater power. Necromancy in itself is a weapon like no other. While there are many who struggle to achieve reanimating the simplest of dead and complex life forms, there are also those who cannot concentrate themselves to bring life back into familiar faces, much less their own kin. If you can do that - if you can reach beyond the false ideologies of those who believe moral guides them - then you will realise that you can attain power like no other. There are truths out there even I have not obtained. But together, we will conquer them. One day, you will teach them to your apprentice, and the descendants of our lineage will be ever stronger."
The Force swayed in its balance. No longer did it feel as if Tennacus was assisting his apprentice with the aid of his necromancy, but more like he was trying to take ultimate control over the risen host. The soils once again moved in accordance to the Force's influence, serving to swallow his brother back beneath their feet, so that he may be risen once again another day. Once the manipulation had concluded, Tennacus' shadow dispersed from the presence of the burial, returning his entire consciousness back to the halls from which their physical guises resided. Before beginning anything else, Tennacus awaited the return of his apprentice, expecting he might have something to say.
