Tribal Liar
The race of Zoons was unable to tell lies, but anyone who could attempt to tell a proto-lie, such as "actually, my grandfather was quite tall" is encouraged to develop their skill, and could eventually become the official Tribal Liar for all the Zoons, and he would deal with all negotiations with other races. Said other races get offended by this and think they should have picked a more acceptable term, like "diplomat" or "politician". The Zoons reply that this is exactly their point. Mentioned in Equal Rites, Amschat B'hal Zoon, was the current Liar at this time.
