Lysidas is a Marik Border World occupied and virtually wiped out by Redjack Ryan while under contract to the Lyran Commonwealth in 3017 (apparently he managed to "poison half the atmosphere" by breaking a fusion plant somehow, I assume magic). However, I find no trace of this world on any 3025 era map, nor on the 3015 map in the Historical:Brush Wars section covering Anton's revolt, nor any other maps for that matter. In fact, the only place where the name Lysidas can apparently be found is in the troublesome Periphery Sourcebook where Redjack Ryan's origins are detailed.
My question, therefore, is should Lysidas be considered an actual Lost system, or should the name be ignored?
