Didn't you say that you saw it around the time of FS1 though? This includes some systems that weren't named until FS2, and even some systems that are specific to the BWO-Derelict continuity.
Which would be when I made Cardinal Spear and Cardinal Spear: Vega where I made a modified version of the FS1 nodemap with Talania added.
So I'm the guilty party. Since then, I decided to retcon it into being a gas giant system in Beta Aquilae
The non-flash 'Cold Element' nodemap used for BWO's command briefing animations had Talania removed.
That map also had N362, which was in my first campaign Darkness Rising (which I didn't know about the OEM version of FS1 at the time...).
