Shara
From Tardis Wiki, the free Doctor Who reference
Shara was a physicist. On Talderun, he created an energy converter that generated a time loop so he could exist in eternal bliss. When a crucial component of the converter (his skeleton) was removed, the imbalance threatened to rupture the Time Vortex. This was averted when Antranak jumped into the converter as a replacement. Shara possessed Antranak, then both died. (AUDIO: Nekromanteia)
