Actually, I was thinking of using the Trojan Horse as a unit.
As for the Arthur quote, supposedly his gravestone reads "Here Lies Arthur,
The Once and Future King"
How about
Bartlet for America: Universities and Hospitals are cheaper (Bartlet passed a Social Security reform bill and a bill to lower education costs)
Other ones:
First Prophet: Scudder, when a state religion spreads to a city, a temple and monastery are automatically created.
Evil Genius: Doom, sacrificing population gives a research boost for every population point lost
Orisha: Shango, temples increase production by a small amount (
Ori, spiritual growth and
Ashe, the will to create - I'm taking this literally as a bonus to production)
Kalachakra: Suchandra, a discount on research cost until the Renaissance.
And I would change Xerxes' trait to this:
1000 Nations, Infantry trains at 1.5 times regular speed.
