MA1 HC MGSc1 / IMB-1c1
But a few scant leagues from the walls of the bustling town of Greyheim lay the crumbling ruins known as the Castle of the Mad Archmage, Jophob Schlech, long shunned by the local townsfolk. Decades ago, a series of vast treasure hoards were discovered in the twisting mazes beneath the castle proper, along with hungry beasts and deadly traps aplenty. Legends were made in that time; the names of those early explorers will live on for centuries. Eventually, though, the dungeons lost their luster as the treasures became smaller and harder to win, the traps were dismantled, and the monsters slain; eventually only the desperate or jaded dared enter the dungeons beneath the castle.
Recently, however, reports have surfaced of renewed stockpiles of wealth in the dank passages and chambers beneath the hillock upon which the stillruined castle rests. Regions once deemed devoid of monstrous habitation have been reported to teem with renewed activity. Traps both magical and mundane have once more brought explorers to their doom. Changes both subtle and gross have been noted in the very layout of the passages and chambers, rendering old maps and knowledge dangerously unreliable if not outright useless. Something is definitely afoot, and most honest folk in the nearby city find the prospect an unnerving one indeed.
To the bold and daring, however, only one message needs to be heard. The castle and its dungeons are once more ripe for exploration, and new legends are ready to be made beneath The Castle of the Mad Archmage!
This new edition contains all 14 core levels, including the surface ruins, the wilderness immediately surrounding the castle, and several sub-levels. It also comes with VTT-friendly maps that don't show trap doors, sloping passages, secret doors, etc. (you'll still need to add your own "fog of war" according to the specific system you use). It is compatible with most old school games, specifically the first advanced edition of the world's most popular RPG.
