Twisted dwarves of Hagiv
From The Thalassan Sphere
Originally the copper and nickel tribes of of the Kiraly Mountain Range, the twisted dwarves were those that suffered from manatite poisoning during the Cataclysm. It left them and their descendants physically and mentally damaged and very short-lived, with an estimated life span of 30. After the Deep Delver Wars, they were enslaved and made to work on Hagiv's farms and build its defenses.
During stressful situations, Twisted Dwarves must make a Willpower Roll (DC 12+ depending on stress level) or they become disoriented. Manifestations of this can include short-term catatonia, lashing out, going fetal, or wandering off in the middle of combat.
Nagev, the Glorious Leader of Hagiv, is by far the most famous of the twisted dwarves.
