Fable's Sword of Aeons established the series' boldest choices

Fable centered its finale on the Sword of Aeons, a legendary weapon Jack of Blades wanted at any cost.

The game’s last major choice forced players to kill Theresa to unlock the sword’s full power or destroy it instead.

That irreversible decision became a defining part of Fable’s identity and a memorable example of moral-choice design in RPGs.
