The concept of a sentient, because why not?
Eianohyaheir or Thousand-Armed Eia, along with Hunhow, is a rather old drone that had a greater specialization in small things and bioterraforming. Its extremities are for the most part - "arms", and the engines and gravitons are located in front - it was conceived, but more will move on land on tentacular manipulators. Many hands, many eyes, as well as a huge supply of energy. He took a lot of inspiration from the nature of calcification and skeletons.
The very last one rolled from Tau to the aid of Hunhow, but completely unaccustomed to using beam and plasma guns in battle, he drowns in the oceans of the Earth, causing a large earthquake by the explosion of his abyss drives. The archipelagos and atolls nearby, or rather their inhabitants nearby, take him for a deity and build a culture around the broken drone, and then they themselves terraform the zone for themselves, building coral-like structures. Eia lurks in rifts and thermal currents where radar cannot inflict it, sometimes attacking patrols in the islands. And the islanders themselves, seeing that their "master" is not like that guys, attack either Tenno or other factions. Eia tries in vain to send a distress signal.
Eia has created Qubehran
