Damn! also my idea seems not working.
I'm not able to find an alphabet shift that satisfy column and repetition restrictions for fitting DARK Region/Sector.
Can anyone suggest me other 6 letter words that can be placed with DARK into a 3 words a system name?
Nebula would fit the 6 letter word![]()
could this help?
The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion, Horsehead would fit your nine letter word nicely, so Dark Horsehead Nebula perhaps?
