Battle of the Cavern
The battle of the caverns was a raid on the Drow encampment amassed beneath Graceport. Various factions within the city (Paladins of Corellon, the Mirror Enclave, the Companions, the City Watch) all participated in the defense of the city. On one end of the cavern, Lord Ghesh (appointed the Lord Commander for the battle) led an all-out assault. On the other end of the cavern, detachments of the City Watch were concealed and muffled to avoid detection as they attempted to destroy the spawning pits of the Driders. In the end, both forces were successful and the Drow suffered a crushing defeat.
Tiandra appeared near the end of the fight and cleansed many of the remaining drow of their corruption. When she attempted to use a powerful rod against Lilith, the rod shattered, and the shards and power of the rod injured Tiandra gravely.
