This was an entry by Pelagius in the BSC (Best Scenario Contest) from 2002. I love the swampland design of this one. My old zip file doesn't have a scenario description though (just a judges' critique and scoring of the map). I couldn't find one either in the BSC threads in the forum.
Anyway, you can check out another great entry in the contest CJ Tarsus by Caesar Jan. It looks like the scenario link is still active in the author's site. Just google "caesar jan geocities"
