Askanj-saeaen

Askanj-saeaen (or Askanj-saean, Proximal Flame used both names) had six legs and they didn’t stand erect like most species.

They were technologically advanced but still pre-FTL species when neo-Luddite movement emigrated with the aid of the necessary sins of an experimental FTL drive and later become Kobolds. Remaining population continued to develop at their own pace. The initial inventor of their version of the shock drive was not only a genius generations ahead of his time, but he was - unfortunately - a member of the separatist movement and when they left, they destroyed all the data they left behind to avoid 'contaminating' the rest of their species with this grievous technological sin. Finding out that hey, those guys weren't just crackpots but had actually developed FTL... and then erased any chance of the rest of the species getting it didn't exactly endear the departed separatists to their kin.

Fast forward a few centuries and the species is on the verge of developing a shock drive. (Again). The Askanj discover them before they really get it off the ground. Later the Yengesae and the Askanj-saean came into contact (and conflict). The latter see the former as deluded fools, helots following their master around for the hope of a kind word and a pat on the head. The former see the latter as arrogant and spiritually stunted. They've bound themselves to a second-rate power, deluding themselves into thinking that they are equals, when they needed the Principality's help to even leave their own system. They've learned nothing in all those centuries...

...just as their cousins would say that they've learned the wrong things.
