Highcliffe Castle is originally a fortress owned by Fierdsvain. A relatively large garrison is in place in this strategic fort.
A secret path runs just to the north of Highcliffe Castle, connecting it to Avendor. Don't be surprised to see it change hands often, because it is a strategic launching point for attacks on Fierdsvain.
Sarleon can shuffle troops through Highcliffe Pass, and most likely will. Ravenstern is also likely to attempt to take it. If they do, they can bypass Mistmire Castle and its constituent, Ibiran. The Fierdsvain will most likely focus a lot of effort to take it back, for obvious reasons.
Its constituents include Nomar.
