Castle Whitestone

Whitestone Castle is a small castle built on a hill to the north of the city-state of Whitestone. Originally owned by the de Rolo family, the Briarwoods claimed the castle for themselves once the city fell under their rule. After the success of the Whitestone Rebellion, Cassandra de Rolo and (in absentia) Percival de Rolo regained ownership.

Description
On the west side of the Whitestone castle is a secret passage leading to the dungeons beneath the castle. It was notably used by Cassandra and Percy de Rolo to escape the Briarwood's assault. A set of wooden stairs led to an undercroft where the bodies of previous rulers were entombed. A more recent long tunnel was dug through the back wall of the mausoleum leading outside the castle toward the Sun Tree to an ancient subterranean ziggurat, formerly a temple to Ioun.

Prior to the Briarwoods' occupation, there was a circle of teleportation in the castle; however, it appeared to have been destroyed as part of the Briarwoods' efforts to further isolate Whitestone from the rest of the world. Another circle was created during Vox Machina's year-long break from adventuring.

Widow's Garden
A poisonous plant garden was planted around 730 PD by Lady Melanie de Rolo, in order to covertly poison her husband. During the Briarwoods' rule, the gardens were left untended and withered. In 836 PD, the garden, now renamed the Widow's Garden, has been reestablished and maintained in party by Keyleth.
