Fantasia Frost is a unique version of an Iron Assassin Golem.

Iron Assassins are articulated iron bodies inhabited by unusually powerful bound earth elementals and covered with extremely effective illusions (visual, audible, smell, touch, heat) to give them a harmless or desirable appearance. They are rare as most of the suitable gnomes were used up long ago. The few functional ones left in Chaos are kept hibernating to prevent the development of odd behaviours. Iron Assassins weigh in at about 1000-2000 lbs, something that is disguised by the illusions and a sophisticated levitation spell.

Frost's spirit is a hybrid, a fused gnome and Abyssal HungryDemon. 'She' eats magic and has been employed mostly as a wizard-killer. She can crush rock with her hands or bitch-slap a charging tiger. Bullets and ballistae bounce off of her; cannonballs bounce her and might take off an arm or leg. She can be welded solid by sufficient sustained heat or current but retains sufficient earth-elemental power to reshape her chassis into functionality.

Frost has been active for over a century and has developed a near-human personality and a strong desire for sensation and a more human existance. Brand saw that her desires dovetailed nicely with his current project and recruited her as a bodyguard and expediter.

Update: Brand did install Frost's spirit in the body of a newly-killed Chaos lady. She has retained her elemental and demonic powers and is looking forward to mastering her body's innate shapeshifting ability.
