Construction beginning/end
Originally before The Solstice of Shadows on the continent now known as the Darklands, The shadow legion built a sprawling near-impenetrable castle where they could fend off any attacks from those trying to stop them. It was destroyed by the great Blade of Shraenire but over a hundred years later the three new disciples of Shraenire were ordered to rebuild it.
Once before the The Solstice of Shadows, the The shadow legion built a massive fortress of black stone bricks right on the area of land now known as the Darklands. Many crusaders of the light would attempt to assail the fortress but they all failed, the fortress is partially attributed to the success of the The shadow legion in summoning Shraenire. It was destroyed in The Solstice by Blade of Shraenire being plunged into the nearby ground. After Unele and the other two followers were sent by Shraenire to the Darklands aboard The Onyxprism, Shraenire ordered them to once again re-build the great black fortress, a task which took even longer than the construction of The Onyxprism.
