Hello I am generic city builder game. You must power your city somehow-- what's that? You want to use nuclear power? Okay, but, nuclear power is unstable, resource-consuming, and polluting. This is definitely how nuclear power works. Also there is no safe way to deal with nuclear waste, definitely not, which by the way is definitely canisters of glowing green goo that get produced by the truckload every day. Now why don't you use hydroelectric, which definitely has no environmental impact whatsoever, or maybe wind and solar, which are definitely cheap, plentiful, and universal solutions. I am a good game.
These ancient mosaic fragments, slightly submerged in the sea, can be found on a deserted stretch of minor road on the East coast of the Greek mainland, untended, unsignposted, unnoticed.
