In the early years of the 3300s, a number of significant discoveries were made; the Unknown Artefacts and Unknown Probe, both of which later transpired to be of Thargoid origin, and the ruins of the ancient civilisation nicknamed the Guardians.

As investigations into these progressed, the Unknown Probe was found to reference a system within one of the mysterious permit locked regions of space; Col 70 Sector FY-N C21-3.

Although the Col 70 Sector contained various unlocked regions which could be accessed, all systems which were part of Col 70 itself remained inaccessible, despite all efforts by independent cmdrs to find a means of entry. Reports of activity in Col 70 by Wreaken Construction lead to efforts to undermine their activities to force a release of permits but all was for naught, and the only further direct information on Col 70 Sector FY-N C21-3 came following the discovery of large unknown structures in the Pleiades, whose unknown devices appeared to contain a stylised representation of the system in their sounds.

On another front, as more Guardian ruins continued to be found, a pattern emerged which allowed an approximate centre to be established what appeared to have been the main region of Guardian space.

A key result emerged from this; Col Sector FY-N C21-3 was closer to the centre of the main group of Guardian ruins than the first Guardian site to have been found.

This opened up the intriguing possibility that the system referenced by the Unknown Probe might have once been within Guardian space.

The result remained as estimates of the centre of what had been Guardian space were refined and ultimately narrowed down to the Regor sector, which like the Col 70 Sector was mysteriously permit locked. However, with not direct access due to the permit locks, and with no ruins found nearby, this line of enquiry ground to a halt.

This changed with the establishment of a relationship between the Guardian ruins and the fungal trees known as Braintrees.

With the type of location which Braintrees occurred becoming well established and predictable, an apparent link between them and Guardian Ruins had emerged, and via checking areas for Braintrees, and thus determining search areas for Guardian Ruins, various small Guardian areas had been discovered throughout the galaxy. Working on this principle a small survey was conducted of the Col 70 border as near as possible to FY-N C21-3 to discover candidate bodies for Braintrees.

Sure enough, on 27th October 3303, Braintrees were found on the first site checked, only 100ly from Col Sector FY-N C21-3.

At this point, hostile reactions from Thargoids to Guardian artefacts had already been discovered, and with a close proximity, if not overlap, between a Thargoid related system and Guardian space established, various questions were left open...

What was the relationship between the Thargoids and Guardians?

Why was there an area in the Synuefe sector with Braintrees but no Guardian ruins? Was this a sign of a conflict with the Thargoids?

What was in the mysterious Col Sector FY-N C21-3 system?

And with the permit locked Regor Sector having been established as the apparent hear of the Guardian bubble, who had put in place the permit locks, and why?
