Who is this Xan anyway???? I have never encountered him or any reference other then the present thread about him! What are his triggers and its fuction?
Xanthippus was Spartan merc who was hired by the Quarthadastim as militry advisor during the first punic war. He was the mind behind the Quarthadastim Victory against Regulus. The full story can be read in the "Year in History" Events.

Well, you have just quoted the triggers for him to enter the game. If those conditions are not met he will not enter the game.
