Around the Rivenhold
The fungal horde come from the north eastern hills, across the planes they spill, death and bizarre outcroppings of fungus left in their wake. They sometimes drag away the living to infect with their fungal disease, making them one of their own.
Their mouths and eyes are filled with small mushrooms and fungi, their skin is a sickly grey palor. They breath ragged breaths and run longer and faster than a normal man should.
