Indigo Prime

Indigo Prime is the umbrella name for a series of stories written by John Smith for British comics magazine "2000 AD". It is about an agency - existing out of time and whose members are dead - which police the multiverse of parallel realities.
Plot.
Indigo Prime is an extra-dimensional agency dedicated to the maintenance and repair of breaks and distortions across the multiverse. However, they're not above making a few 'alterations' for any rich clientele that approach them (although it appears that this is never at the expense of the harmony of the multiverse itself). Their base of operations exists outside the multiverse and time itself in a hypothetical 'nullzone', which every event in time and space throughout the multiverse transects.
All Indigo Prime agents are chosen, upon their death, based on the presence of a certain gene (the "Rembrant Index") that occurs in one in twelve million people across the multiverse; given a new body, and then trained in a range of abilities to assist them in their job. Each agent also specializes in a role - known job descriptions are: Sceneshifters (who manipulate the physical world), Seamsters (who deal mainly with time) and Imagineers (who can influence minds and dreams).
Publication.
Initially appearing in the "Future Shock" "A Change of Scenery" (prog #490) the agency was named "Void Indiga" but changed after Smith learned of Steve Gerber's graphic novel "Void Indigo". Indigo Prime agents then featured in eight illustrated comic stories in "2000 AD", two text only stories, and had cameos in a number of stories about Tyranny Rex, as her stories also occur in the Smithiverse" " Over twenty years after the last of the original stories was published, Winwood and Cord made a surprise appearance in the last few pages of supposedly unrelated and standalone serial "Dead Eyes". This subsequently dovetailed into the first new Indigo Prime stories for two decades.
From episode 3 of "A Dying Art" in "2000 AD" #2052, Smith was replaced by Nigel Long, under the pseudonym "Kek-W".
