Oh my, these guys are a proper Death Star. You think tha's a friendly moon in the shape of a big round gold coin, but it has a sturdy structure - the EQ is akin to a holy site or a wonder stability-wise, and then you realize that the yellow shiny hue indeed comes from the Death Ray in the shape of Mtepe - it hits the overseas opposition before they even reach the middle hill in the "w" of "wha'?" Especially if you couple it with the Lighthouse of Alexandria and whatever troop movement bonuses can be picked up on the way.
