Larivan
From Tardis Wiki, the free Doctor Who reference
Larivan was a slave of the infinite warriors. The Eminence wanted him to take the breath of forever and become part of the Infinite. He met the Fourth Doctor and Leela during his transformation. He wanted the Doctor to warn his family. He noticed Sarla and Tillegat among the construction workers[statement unclear]. The Doctor tried to rid him of the Eminence conditioning.
