Forge a Legendary Magic Item with Narrative Weight

A +2 sword is loot; a legendary item should be a story players argue over. Give it your system, theme, and level, and you get a name and description that hint at its past, an in-world inscription, a balanced primary effect, and an attunement drawback that bites. The kind of item a character is named after later.

Design a legendary magic item for a {SYSTEM} campaign. The item should fit a {SCHOOL_OR_THEME} theme (e.g. necromancy, time manipulation, elemental fire). Provide: (1) a name and physical description that hints at its history, (2) a lore paragraph written as an in-world inscription or scholar's note, (3) its primary mechanical effect balanced for {CHARACTER_LEVEL} characters, (4) one attunement drawback that creates interesting roleplay pressure rather than simple stat penalties, (5) an escalating power progression: describe what happens when the item is used for the first time, after a significant story milestone, and at the campaign's climax, and (6) a quest hook for how the party might discover or acquire it. Avoid simply copying existing items; the mechanics and lore must feel inseparable.
