They are boastful and arrogant, and injury only makes them stronger. \n'b'  Relentless Agents . Fierstjerren carry out the orders of their creators with independence and foresight, while others independently further the cause of evil as they see fit. \n'b'  Malevolence Under Tension .

When the fierstjerren is wounded, the spirit tears free, animating the twice-undead corpse in a burst of necromantic destruction. \n'b'  Accompanied by Zealots . Fierstjerren are often accompanied by a dozen thralls-humanoid zealots serving the cult, willingly or not, who view the fierstjerren as an avatar of death and will follow it to the grave and beyond. Thralls attack under the direction of the fierstjerren, who is alerted to any danger the thralls perceive. A fierstjerren will sacrifice its thralls without remorse to secure an advantage, a sacrifice that is often seen as an honor by the zealous thralls. \n'b'  Undead Nature . The fierstjerren doesn\xe2\x80\x99t require air, food, drink, or sleep.'
