Sorry for not posting for a while, i have been busy packing for Uni.
This is a concept / ref of one of the sub species of Keiscarans (they are a major species I made for my world building/story). These are specifically Builder Keiscarans which are in charge of upkeeping and building the lair of Keiscarans, Havesharek.
Havesharek is underground, structured similarly to an anthill which is why corridors and rooms need to be dug out by these keiscarans.

[TW: Mentions of violence/war]
Keiscarans are an important species, they worship the God of War, unnamed, and they were made from his blood after he had been trapped in another dimension following a war between the gods caused by him. Keiscarans are spiteful and sadistic, following the ways of their god, causing unnecessary wars as a way to worship the god. Builder keiscarans rarely have a role in the wars, but sometimes they are used to weaken the foundations of fortresses and cities so they collapse.
