Delduin-class Generation Ship
As the worldstorm consumed the last remenants of habitable locations on Blimnor, the dwarven nations finally conceded that they would have to take to the stars as their fellow races had done before them. However, with considerably less time to research effective rocketry, technology, and comfort, they were forced to hastily design and launch the ships that would ferry them to the next habitable star system.
Nonetheless, the Delduin-class generation ship was an impressive craft, nearly doubling the mass of its counterpart, the Exodus-class.
However, with the technological limitations, the dwarven engineers had to suffer a number of inconveniences.
First, without constructing the massive centrifuges that the Exodus benefited from, they were forced to use large rectangular outlying pods whose shape could not sustain consistent equivalent gravity and were difficult to access without EVA.
Second, in order to accelerate manufacturing, most modules were designed to be identical and assembled like cargo crates. As a result, design flaws were rampant as modules frequently became disconnected or suffered other malfunctions, requiring constant maintenance.
Third, with most of the spacecraft not designed around centrifugal artificial gravity, the dwarves had use constant acceleration in order to generate the needed gravity. And in their determination to reach their destination, spent most of the trip enduring greater than 1g of force.
Finally, and most astonishingly, the dwarves did not have access to cryostasis technology. While their fellow exodians could spend dozens of years in blissful frozen sleep, the passengers of Delduin ships were forced to live, breed, and die for a hundred years before finally arriving in the Eddom system.
Beyond the tragedy of the original crew never surviving to see their new world, multiple wars, mutinees, diseases made life on these ships often unbearable. And upon the completion of the journey, the dwarves still alive found it hard to integrate into the exodian culture that had 50 years to develop, to say nothing of the aggression, isolation, superstition, and mental illness that had taken root in the new generations.
One genuinely excellent design of the Delduin which is often overlooked is that its modularity was ultimately a great advantage. Each component itself was equipped with excellent thermal shielding, allowing the ship to be taken apart piece-by-piece and dropped from orbit onto the surface to serve as pre-fabricated structures for early dwarven settlements.
On the whole, while the Delduin may pale in the shadow of ancient dwarven craftsmanship, it undoubtable provided the sort of hardships that bring out the best of dwarven endurance.
