AC2: The Treasure of the Hideous One

"The Treasure of the Hideous One" by David Cook is a mini-adventure for character levels 4-7, set within the Grand Duchy of Karameikos.

A "treasure map".

Cook provides a glimpse of the earlier history of the Grand Duchy of Karameikos in the background:

The expedition was undertaken 100 years ago by Colonel Rosentos.  The colonel led a troop of 200 soldiers, most of whom were on foot.  Duke Stefan the Hermit ordered Rosentos and his troop to explore and claim the lands to the west.  At that time, the duke's lands were very new.

The Treasure of the Hideous One

I used this information in my article "Karameikos: The Hidden Years" published in Threshold #1, to reconcile the adventure with material in GAZ 1 "The Grand Duchy of Karameikos".

Location:

The adventure takes place in the northwestern part of the Grand Duchy, although the native villages seem out of place.*

*I wonder whether Cook used material originally intended for I1 "Dwellers of the Forbidden City"

The lagoon lowlands of Serpent Peninsula or swamps of Thanegia Island work as alternate locations in the Mystara setting.

New Monsters:

Cay-men, Giant Serpentweed
