The Palace is the key (and possibly only) setting of The Play and location of The Party. Most interpretations place it on one side of Lake Hali with Carcosa on the opposite shore. In Delta Green: Countdown, it is the palace of Yhtill, the only part of that city not fully absorbed into Carcosa, but laying across the lake from it. In The Night World setting of Insylum RPG it is termed The Castle.
