Looking at the edit records on the NSwiki page for Forest, the earliest mention of Karock is 10 June 2006 where I recorded that:
There are currently 8 nations active in the region. In order of regional influence they are: The Cool Temperate Rainforest of Errinundera: superpower The Kingdom of Karock: superpower
Given that I recorded you as a superpower, you have been around some time before that, Karock. I re-activated regional control on 3 May 2006 - were you around at the time? It seems likely but my memory isn't so good.
BTW, Errinundera was born on Christmas Eve, 2002. I had two years off between November 2003 and November 2005. Obviously I moved to Forest sometime between November 2005 and May 2006.
