Before making a return trip to the Omega Octant, there is a territory located along the Galactic Rim of the Alpha Octant which is of note: namely, the
Vudar Enclave.
-----
The reptilian Vudar are native to a world in
Federation and Empire hex 1619, close to the Galactic Energy Barrier, with is exposed to a higher than average degree of radiation than most Class-K/L/M/N/O planets. Thus, while the Vudar themselves - who, after all, evolved in this environment - have no problems with this, most other species have great difficulties surviving there.
Thus, when the Klingons arrived in the system during the Early Years era, they found themselves obliged to enter into a looser system of suzerainty over the Vudar, as opposed to the norm imposed on most other subject species of the Klingon Empire.
Over time, this "satrapy" arrangement was expanded and built upon. The Vudar, who were found to have a particular knack for building and operating impulse engines, offered a steady supply of these drives as part of their tribute to the Empire. In return, the Kiingons permitted the Vudar to operate a number of Middle Years ships, which were tailored to operate close to the Barrier in ways the Klingons themselves found more of a challenge. Gradually, the Klingons turned over more and more territory for the Vudar to patrol (with half of these areas' economic income going to Klinshai as tribute), as well as permitting the Vudar to field more and larger ships in their fleet.
Late in the General War, as the tide began to turn against the Coalition, the Klingons launched a diplomatic gambit: using some "creative" record-altering, they made it seen that the Vudar, having used a hidden shipyard to build more ships than had been permitted, succeeded in breaking away from the Empire and establishing the Enclave as a neutral power - one which, conveniently, happened to hold three of the Hydran Kingdom's pre-war provinces, plus a part of the pre-war Hydran/Klingon Neutral Zone. In truth, no such hidden shipyard existed: the Enclave remained a loyal satrapy of the Klingon Empire, albeit with perhaps a bit more autonomy than the more traditionalist groups within the Empire proper might have liked.
While the Hydrans were not fooled, they nonetheless accepted this political fiction, as it shortened the front line between them and the Klingons at a time when they were still struggling to liberate their capital world. The Federation, it seems, was more taken in by this gambit, or at least
wanted to believe it long enough to convince themselves to spend the next major strategic effort against the Romulans rather than against the Klingons.
The ISC didn't appear to be fooled either. While they considered the Vudar on the "old" Klingon side of the border to be an internal matter for the Klingon Empire, they insisted that the Vudar withdraw from the pre-war Hydran and NZ space they still held by the time of the Pacification. There wasn't much the Concordium could do about this before the Andromedan invasion swept in, however.
The fate of Vudar-Klingon and Vudar-Hydran relations post-Unity remain to be decoded from the Air Force data tapes at this time of typing.

As noted above, Vudar ships have certain benefits - as outlined in
Federation and Empire: Minor Empires - when operating close to the Galactic Barrier.
Beyond this, they use a combination of Klingon technologies (such as Klingon-type engines on their ships) and systems of their own design.
They have a unique capacity to "ionize" energy generated from sources other than impulse or APR boxes; this is needed in order to operate certain Vudar-specific technologies, as noted below.
Their primary heavy weapon is the ion cannon, which is a two-turn arming weapon. In terms of effectiveness, it sits somewhere between a Klingon disruptor and a Federation photon torpedo. Notably, it requires at least one point of "ion" energy (from impulse, APR, or "ionized" power from other sources) to arm; as a result, while Orion Pirates in Vudar space can make use of these weapons, they seldom bothered to do so. Vudar fighters had a smaller version of this weapon known as the ion pulse cannon.
As a support system, their ships have ion pulse generators installed. All of the energy used for the IPG must be impulse, APR, or "ionized" power, though each generator has its own built-in capacitor. It can be used in one of two modes: to "produce a "jamming" effect (three points of "natiral" ECM per point used), or to produce a defensive ionic wave (which impacts nearby shuttles and drones).
Bases - be they "deep-range" facilities with active positional stabilizers, or facilities placed on atmosphere-less moons or asteroids, can be given large or small ion storm generators. When activated, large ISGs produce an "artificial" ion storm
61 hexes across; small ISGs "only" produce one that is 25 hexes across. Both types can fire a "directional" burst of energy, in which case it scores damage against all units within range and arc of the generator so used. (It was the timely deployment of these generators which was leveraged by the Klingons in order to explain why the Vudar were supposedly successful in gaining their independence from the Empire.)
Other Vudar weapons and systems, such as phasers, fighters, and PFs, are more or less in line with "standard" Klingon technologies - though the Vudar preferred to operate their own attrition units rather than "importing" Klingon designs.

A good case of Vudar starship technology is their heavy cruiser.
In certain ADB art works, the Vudar are shown with their own type of warp nacelles; as had been shown on Shapeways, however, the Vudar CA in fact had Klingon-esque warp engines.
As for weaponry, the fully refitted CA has six phaser-1s, two phaser-2s, two phaser-3s, four ion cannons, and two ion pulse generators. It has a Turn Mode of C, making it closer to a Lyran or Hydran cruiser than to a Klingon D7 in terms of agility. In keeping with the need to produce "ionized" power for said ion cannons and IPGs, this ship has a relatively large number of APRs to supplement the power provided by its impulse deck.
While the CA is a capable ship of its type, there never were very many of them; the bulk of the Vudar fleet was comprised of smaller warship designs.
