This new unit is available with Monarchy. It is essentially identical to a Diplomat - he can <l:6,36>establish an embassy<e>, which allows one player to monitor another Civilization's progress and allows Civilizations to exchange advances through <l:6,67>diplomacy<e>; and he can <l:6,55>spy<e> on a foreign city. However, unlike Diplomats, Nobles are unable to see <l:1,11>Clerics<e>, <l:1,5>Slavers<e> and <l:1,23>Abolitionists<e>.
