Autloc

Autloc was an Aztec High Priest of Knowledge in the 15th century. When The Doctor and his Companions arrived in the TARDIS, Barbara Wright assumed the identity of an ancient priest. Although Tlotoxl was against her, Autoc supported her, even when she tried to end the practice of Human sacrifice. Autloc ended up sacrificing his position to help them escape. (DW: The Aztecs)
