When designing the Sher’Tul, Amakthel had numerous failed experiments. Rather than dispose of his misshapen creations, he ignored them and left them to their own devices. They multiplied and spread through Eyal’s underground. However, Amakthel wasn’t wholly responsible for this plague. The Sher’Tul also created many bio-weapons during their civil war. They engaged in the same sin as their father and reshaped life for their own ends. They degenerated their own brethren, mutating them beyond recognition. To their credit, they tried to clean up the remnants of their war, but some horrors escaped their notice. There are also horrors which came to Eyal from space. All three of these groups are collectively referred to as eldritch horrors. I have catalogued various types of eldritch horrors below.
