Kush is another of the odd people the make up Tancred's inner circle. Standing around four and half feet tall, Kush is shorter than most people. He is, however, very heavily built, with a extremely heavy bone structure, and muscles out of another world. Born on the squat homeworld Gamma Sigma Serpentis Secudus Kush witnessed the destruction of his home at the hands of Hive Fleet Behemoth (250 years or so ago). He was subsequently recruited into the Inquisition by Tancred, making him the second oldest of Tancred's companions of old.

The squats hold technology in high regard, much like the Adeptus Mechanicus. They do not, however, follow the teachings of the Machine God, but have accepted the Father of Mankind as their own (in addition to their own version of ancestor-worship). That said they are as superstitious as all the other tech-priests, so no difference there. Some squats make a living as part of the many techno-guilds throughout the Imperium. Kush is head of the Haegum's technical department.

Yeah, GW killed of the squats as well, something about their worlds all having conveniently been eaten by Hive Fleet Behemoth. Probably had their reasons, but I don't see why the ratlings and squats had to go, while the ogryns stayed? Whatever; as with the ratlings the squats are hereby back...and as with the ratlings they are not comic relief. They evolved (or perhaps genetic engineering was utilized, who can tell after all these years) over thousands of years on high-G worlds near the galactic core, worlds that were often very hostile (but mineral rich), which forced the squats to spend much of their time underground.
