Miliard's haste and arrogance would be his downfall, however, for his searches lead him to the spirit of an ancient Sith warlord. Bound forever to the ruined mausoleum, the Sith imprisoned Orocus and subjected him to a nightmarish Derriphan – a creature created from the Dark Side of the Force, which was capable of devouring the thoughts and experiences of beings and leaving them nothing but an empty shell. Over the many centuries that had passed since the Sith's demise, the Derriphan had grown weak and could not fully consume Miliard – but rather held him in a stasis of half-life, neither-living nor dead. A delicate symbiosis formed between the pair. The Derriphan could sustain itself only so long as Orocus was alive, and so did not drain him completely.
