Actually it is in the Wing Commander Universe, just in a very remote part of it.

The crown jewel of the Antares Quadrant is the Polaris
Roads Naval Station, formerly home of the Terran Confederation’s
15th Fleet. Polaris is a massive space station, its
environs including berths large enough for even Hvar’kann
and Behemoth-class dreadnaughts. At its heart, the station
is the center of commerce for the frontier: savvy consumers
can find everything from Kilrathi Durasteel to biopolys
from the distant Tri-System. As a result, the base has
also become home to a continual melee between mercenaries
and pirates seeking to take advantage of long haul merchants. Whether you’re
looking for an engine upgrade or a pirate bounty, Polaris Roads is the place to visit.

Rein Ertrobs releases the fourth book in
his wildly popular series of fantasy novels
set within the Darkening universe. The
book, entitled Lev’s Pact, forces the publisher
to restructure its flat-scan transmit
hub in order to accommodate the over
one billion requests.
It's in the Wing Commander Universe, it just has nothing to do with the Terran Confederation or the Kilrathi. It has another government in the same galaxy though.
