Ancient Basin

A Stag Station located on the eastern side of the Palace Grounds which can be reached after destroying the breakable wall near two Royal Retainer corpses.

Since it was hidden, the Last Stag was not aware of the station's existence. Numerous spools of silk can be seen in the background of Hidden Station.

Trivia
 * During development, Ancient Basin took the place of the cut Forest of Bones area. As can be seen on an early map, before the Forest of Bones was cut, the Palace Grounds used to be much bigger. It also would have been the place where Dryya could be encountered. A concept sketch shows what it would have looked like and that its name was "Imperial Grounds". The current Palace Grounds were also shown in a sketch under the name "Royal Bridge".
 * The Monarch Wings are likely what cause the torrents of wind in portions of the Ancient Basin, as picking the Ability up stops the wind.
