Add a race of scorpion called Scorpian. Thay have mutated under the influence of human activity and acquired a human-like appearance and intelligence.
They look like young, slender females, but their length exceeds two metres and they have huge tails that can reach three metres.
They have a venomous stinger at the end of their tail and prey on prey immobilised by their venom, which they cut into small pieces with their huge shear-like arms extending from near the back of their heads.
They are highly intelligent and, with education, can use tools as well as or better than humans.
Their fundamental thought processes are largely unchanged from those of wild scorpions.
They are indifferent to many things that make humans uncomfortable, but what makes them happy is also slightly different from that of humans.
They can emerge from a insects hive.
They may have joined the insects hive because their interests were aligned.
As there is no home faction for them.
If you want to join them to your faction, you might want to look for a insects hive.
