Construction beginning/end
The Black Tower, restored and piloted by Robin Adlehyde, returns to the sky above the Reach Unsung.
Over the coming months, it is used by the Black Dragon Heroes as a staging ground for the War of Greenskin Plains and (briefly) houses the newly assembled Black Dragon Library under Archmage Simbledon's direction.
On the 3rd of Ches, its Chronogates are activated one last time to send the Allmother Feyndovul to fight in the last battle against the Dark One. The Tower is then destroyed by its creator and falls from the skies over the Sandsea.
