A while back I decided to spend a day or two looking for seeds with Terran worlds in Duzahk, the following seeds were all found in Vanilla 0.9.1a and will be ranked in order of best to worst in my opinion. I will be ignoring Aka Mainyu and Druj in the descriptions because they always spawn in Duzahk.
