Ethric

Etheric was a member of a primitive tribe on an unnamed planet. His species lived in an accelerated time stream, meaning centuries passed for them while seconds passed for others. He lived near the First Doctor and Ian Chesterton, who seemed to be frozen in time. During his coming-of-age ceremony, Ethric was sent to give an offering to the Doctor and Ian. He didn't understand why they had to do this, since the Doctor and Ian never seemed to respond. His father, Kilik, was able to convince him that the tradition was an important one, even if the Doctor and Ian didn't acknowledge it. (ST: Rise and Fall)
