The netherbroods are a humanoid race that lived in the nether.
Eventually their ancestors where the ones who built the netherfortresses but if so their descendants,the netherbroods, lost all of that knowledge about craftships and eventually degenerated.
Lifestyle
Netherbroods usually life in the nether in hidden caverns where they don't have to fear bigger predators.
They build small shelterlike caves inside those caverns where they usually sleep and farm mushrooms which they need to survive as there is no different foodsource around.
Some more archaic groups farm netherwarts or even life in the remains of the earlier netherinhabtitans as slightly more than ruindwellers hiding from blazes.
Few netherbroods have reached the overworld through a portal.
If one of them gets there by chance he often starts to "corrupt" the overworld with netherrocks so he can life in a place where is adaption to the life in nether comes to use and he can use the overflow on ressources the overworld grants.
Appearance
Netherbroods are usually humanoid creatures adapted to the life in the nether but their appearance can differ since different areas in the nether might influence their evolution.
An average netherbrood has the same height as a human and also the same ammount of legs,arms,heads etc.
Their biggest difference is propably their skin colour which usually differs from red to darkbrown to make it easier for the netherbroods to hide in the nether.
Also their skin and muscles seem to be thicker and stronger than those of a human which seems to be neccesary since there are only few netherbroods who have tools so they dig only with their hands.
Since most netherbroods are caveinhabitants in the nether their eyes usually are larger than those of humans so they can capture every little bit of light.
The horns that most netherbroods have seem to be a tool sometimes and a dimorphism the other time to impress other beings or netherbroods.
