Lady of Pain

The Lady of Pain was the enigmatic ruler of the city of Sigil.

Relationships
According to the great wizard Mordenkainen, the Lady of Pain had some sort of connection to the Raven Queen, another enigmatic character. It was said that only the Lady of Pain knew the Raven Queen's true intentions.

History
In ancient past, it was said that an entity challenged the Lady's control over Sigil and nearly defeated her. The Lady of Pain was not able to destroy him; she could only entrap his spirit in a gem, known to history as the Labyrinth Stone, which was lost for over 10,000 years.

This was not the only time that someone dared challenge the Lady of Pain's power. Sometime in the 14 century DR by the counting of years of Faerûn, Duke Rowan Darkwood, a former leader from Vaasa titled the Protector of the North and Guardian of the Great Glacier, rose to power in the city of Sigil. Over the course of only a single year, he became the factol of the Fated faction, and only a few years after that, he even sought to challenge the rule of the Lady of Pain herself, starting the ordeal known as the Faction War. Through years of searching, his servants eventually brought to him the Labyrinth Stone, which he hoped to use as a weapon against the Lady of Pain by releasing her ancient foe.

Naturally, the Lady of Pain intervened to stop the war, sending most of their factols into her mystical mazes, including Rowan. Rowan had planned for this, and with the use of a wish spell succeeded in exiting the Lady's labyrinth. Only, she outwitted him yet again. Her magics were so powerful that he exited the maze into a time some 500 years in the past with no way to return to the future.

Over the next half-millennium, his lifespan extended by magic, Rowan, now renamed Gifad, was imprisoned and driven insane, yet still with enough intelligence to await for when he might be able to meet the "younger version" of himself and attempt his plot a second time.
