You're trapped in a land where musical instruments are alive¸ and music itself is created. But beware ‐ there are dangers aplenty beyond the living instruments who serve the King of All Instruments. Criminals¸ demons¸ monsters¸ and even weird creatures to whom music itself is anathema all stand in your way. Can you find your way home from this bizarre and fascinating place? Musicland can be used as a stand-alone adventure or as an expansion to the Castle of the Mad Archmage megadungeon campaign. Musicland is written using the Adventures Dark and Deep rules¸ and is compatible with most Old School type rules with little or no conversion needed.
