IST Dark (formally known Krypton-1 and unofficially known as IST-2) is an alternate where the International Super Teams were created as part of a plan by someone to control the world; individual IST members may or may not be aware of this.
Krypton-1 is troubling even though it was not an echo of Homeline it was Centrum's first attempt to move a timeline to a closer Quantum....and it succeeded in Centrum year 2005 (local 1981). Centrum then tried to shift the reality back to Quantum 6 and use it as a base in its battle with Infinity.
This shift may be explained by its "near twin", IST (aka Krypton-2), which is a few “decimal places” out of where quantum parachronic theory says it should be making it a "quantum faultline". This would create great concern as Krypton-1 was originally in Quantum 6 while IST has, as far as anyone can tell, always been in Quantum 3 upsetting all theories regarding echoes being close to their "home" reality.
If one uses the idea suggested in Bob Schroeck's blog regarding IST and ITS Dark being near "twins" in the same quantum then Centrum succeeded in moving the reality but messed up and kicked Krypton-1 all the way down to Quantum 3 (making it an even greater quantum shift then what happened to Engstrom) This also means that Centrum may be less inclined to shift close parallels like Krypton-1 as the first time it was shifted it caused a domino effect. It was only a bunch of rouge Centrum agents blowing up London in 1903 on an unnamed echo that Centrum reevaluated moving realities.
