The Lost Continent of Ku is - or rather, used to be - a very small continent about one and a half thousand miles Widdershins and slightly Hubwards of the continent of XXXX.

Mentioned only in Eric, It is possibly Discworld's Atlantis, but whereas our world's lost continent sank extremely quickly, Ku took about thirty years to completely subside. Its inhabitants spent a lot of time wading. It has gone down in Disc history as one of the multiverse's most embarrasing continental catastrophes.
