Castle Dunbarton. For years, the castle was an all but forgotten ruin in southwestern Daggerdale, until the Kingdom of Cormyr took an interest in it, quietly refurbished it and just as quietly planted a contingent of Purple Dragons in it. Zhentarim agents still at large in Daggerdale have begun taking an interest in Castle Dunbarton because they have become aware of the Purple Dragon presence there. Randal Morn also has begun taking an interest, because the Zhents are interested, although he's not yet aware of the Purple Dragon presence.
