No, it's a system on the FS2 starchart. But officially it's one of those FS1-2 inconsistencies.
It is Talania, not Talnia, that was my bad when making Cardinal Spear over five years ago.
At that time, I had it as a system connected to Vega and Beta Aquilae.
However, when doing some rewrites for the new version that will be released with the FS1-2 Conversion stuff thanks to Goober and the good folks working there Talania is a gas giant system in the Beta Aquilae system.
This of course isn't consistent with Eishtmo's story for the V-T war (also interchangably called the T-V war), but since there is no canonical information on wether Talania is a system as in "The Jovian System" or a star system I decided to switch to the former just to confuse the whole FS community

There are, however, some subtle nods to the V-T war project as well as the new version of Cardinal Spear, now titled "The Vega Engagement" in act two of Blackwater operations.
Also, the only starcharts that had the map was a modified version of the FS1 chart I made for Cardinal Spear, which was often "borrowed" and was not labeled as a campaign map, as well as an early version of the Warzone starchart that included systems such as the neutron star N362 and Gehenna.
The only difference between the official nodechart that can be downloaded at the Volition FS1 website and the one used in the command briefing animations is the removal of the other nodes from Sol.
Talania and Gulnara are both the phantom star systems of the Terran Vasudan War
