Alright, can I call this a finished product now?
THE ONE RING [-3]
Description: A simple gold ring. The Dark Lord Sauron invested it with most of his power, and if he should recover it he will surely conquer Middle Earth. The One Ring is semi-sentient, and those around it are frequently enslaved by its power.
Musts: You must have an aspect related to your possession of this item. This aspect should reflect your relationship to the Ring and the level of control that it has over you.
Note: Not every bearer of this item gets every power that it has to offer. Everyone gets Invisibility, but Demonic Co-Pilot is only gained by characters of unusual skill or power. Only major supernatural beings get One Ring To Rule Them All. Everyone except Sauron gets Corrupting Influence.
Skills Affected: Discipline
Effects:
[-0] Purpose. The One Ring was created to bring Sauron dominion over Middle Earth. It may be used for any purpose, but its wearer and those around its wearer will often receive compels related to this purpose.
[-0] It Is What It Is. The One Ring is a ring. Pretty ordinary looking, except for the words that appear when it is burned.
[-0] Unbreakable. As an Item of Power, this item cannot be broken except by the fires of Mount Doom.
[+1] One-Time Discount. The One Ring is small and easily concealed.
[+2] Corrupting Influence. The One Ring slowly takes over the mind of its wearer. Treat as Feeding Dependency, except that the wearer may not recover his Hunger stress by any means.
[-0] Unnatural Vitality. The One Ring keeps its bearers alive, no matter how badly the passing of time might wither them. This power is mechanically identical to Wizard's Constitution.
[-3] Invisibility. The One Ring turns its wearer invisible, creating a strength 5 veil that does not impede the vision of its wearer.
[-1] Demonic Co-Pilot. Uses the Hunger stress track instead of the mental one.
[-2?] One Ring To Rule Them All. The One Ring allows its wearer to inflict compels on other characters who have rings of power. The first such compel made against a given character each month is free, each one after that costs a Fate Point or a point of Sponsor Debt.
