Nation/WMG

The islands are what's left of Atlantis.

An ancient civilization destroyed by the sea a long time ago. It just makes sense. Ok, so it seems to be on the wrong ocean. But what kind of legend is 100% accurate? 

• • There's a mythic civilization of Mu supposedly located in the Pacific ocean. Depending on who you ask, it's either separate or synonymous with Atlantis.

Cox is to Carcer as Dr Rijnswand is to Rincewind.

That is, they're alternate-universe analogues of each other.

• ...perhaps suggeting that Nation and that scene in Color of Magic actually take place in the same Alternate History version of Roundworld?
