Being a Series Outlining the Members of the Post-Apocalyptic Pacific Northwest's Preeminent Political Power, Part the Third:
The Mount Hood Banate. (Population: 25,000.) Atop this active volcano rests an enormous, geothermal-powered military base and weapons factory constructed from a rift-disrupted spaceship. Over the last decade, the now stranded crew have retrofitted their craft into a combination of fortress and factory which they call Tharna Ulthesse in their native language. Their neighbors, however, simply refer to the base as "Mount Hood" or "Pilot Mountain".
The exact nature of these former soldiers is unclear. They are fully human in appearance, but with some interesting deviations from the norm. They are typically left-handed, and careful examination reveals that their internal organs are in situs inversus; that is, they are located on the opposite side of the body than they would be in a typical human being (with the heart on the right, liver on the left, etc.). Additionally, though there seem to be multiple ethnicities among them, many have combinations of hair, skin, eye color, and other characteristics not seen on Rifts Earth prior to their arrival. Magic and psionics were apparently previously unknown to them, though a majority of them have a least a few cybernetic implants or bionics, which are often intricately crafted, even beautiful. (Indeed, some are known to have implants that are entirely cosmetic.) Their language has thus far proven completely unrecognizable to any inhabitants of the Pacific Northwest, as has their culture and religion. They are familiar with the planet's geography, though their detailed maps show several major differences -- Atlantis, for example, is absent from their charts.
That these people originated on a highly divergent parallel Earth seems likely. As is often the case, their arrival on Rifts Earth was an accident. Apparently, in their reality, much of the Earth had been conquered by an invading alien race, and their ship, the Ulthes, was part of an effort to reclaim the planet. Their enemy used an unknown weapon against the expeditionary fleet, which evidently snatched the Ulthes, a mobile base intended to be to planted on the Earth's surface as a sort of staging ground, from orbit (and from their universe entirely). The rift from which their spaceship-base emerged was many miles away from Mount Hood. Disoriented and confused, the Pilots attempted to leave Rifts Earth entirely, but the Ulthes was badly damaged by the orbital satellites and debris field enveloping the planet (something of which they were unaware). They managed to steer their massive craft back to the surface, selecting Mount Hood as the best location for them to regroup, since they would be able to tap into its magma chamber for their energy needs.
The crew found themselves stranded in a familiar world that was nevertheless beyond their understanding: a world where their language was unknown, aliens lived alongside humans, regular attacks by nightmarish creatures were commonplace, and magic, an impossibility, was real. Perhaps understandably, the Pilots reacted to the inhabitants of the region with belligerence for several years after their semi-controlled crash landing. Early offensives led against the often-lawless local settlements in an overzealous attempt to "secure the area" and obtain food and basic supplies quickly degenerated into pointless aggression perpetrated by frustrated (and, ultimately, frightened) soldiers who had lost their purpose. Those that lived in the area surrounding Mount Hood were likewise terrified of the sudden appearance of strange-looking mecha, piloted by hostile people that looked human, yet unfamiliar, and shouted at them in an incomprehensible language.
Eventually, the Pilots, as they came to be known, started encountering determined resistance to their assaults, particularly from Weirminster and the Barony of New Bizantium, and even began to lose men and mecha in these military engagements. Soon afterwards, an officer named Hathli managed to convince many of her comrades that their leader, Sevna, had been rendered mentally unstable and unfit for command, and relieved him of duty after a brief and bloody coup. Hathli informed her troops that they were not going to be returning home without aid, and that they would concentrate on building alliances with their neighbors in the hope of doing so in the future. She declared herself Ban (military governor) of Mount Hood and the region around it, and arranged for a meeting with the representatives of the adjacent city-states. With the aid of a Tongues spell cast by a Weirminsterian Techno-Wizard, her overtures of peace were accepted, and the Northern Cascades Combine, an organization that had originally been proposed to defend the city-states of the Pacific Northwest against the Pilots, was officially formed.
In joining the NCC, the Mount Hood Banate (as it is now officially known) agreed to supply its neighbors with aid and weaponry, an obligation which it has begun to fill in recent months. Under the direction of Ban Hathli, the factory portion of the base has been named "Ulthesse Mechatronics" and has started to provide jobs and training to a select few non-Pilots, most of whom are humans that have chosen to live and work among their extradimensional cousins and communicate with them via Weirminster-manufactured TW translation devices. These men and women live in a swiftly expanding shantytown set up outside of Tharna Ulthesse proper, and are derisively known as "Hood Rats" by those who still hold a grudge against the Pilots. (It is widely believed by their neighbors that Mount Hood was allowed into the NCC as a member state only because the others were either afraid of further conflict, or wanted access to their advanced armaments. Many Pilots, likewise, have not warmed to the idea of "settling down" on Rifts Earth.)
Ulthesse Mechatronics vehicles are large and somewhat ungainly in appearance, but their use of lightweight ceramic armor, supplemented by high-powered force fields, means that they are as agile as any war machines on Rifts Earth. In fact, most UM mecha, even the largest, are capable of short-term powered flight. The "reporting names" the feudalistic Barony of New Bizantium gave these war machines during their conflict with the Pilots have stuck, meaning that most of them have unusual nicknames like "Mantyger", "Yale", "Basilisk", or "Zilant", all derived from fantastical or heraldic beasts. Though they are not mandated to do so by the terms of their NCC membership, Ulthesse Mechatronics is also considering mass-producing and distributing their unique cybernetic implants and bionics.
