[Graeme Dice]

Your unit description might read better if the wording was changed a bit. You might like to try something like:

"A atrange creature the size of a man but with 3 eyes. He hides beneath a robe that emanates a glow that cannot be from this world.
He was sent from another realm by his master to unitie this world, and supply his master with everything this world has to offer: people, goods, magic.
Some say that there is another reason that the ambassador wants to unite the world: To establish his own kingdom and obtain the power to kill the one who sent him here."

Or something like that.
