From publisher blurb:
Long forgotten, the Mage King Althos, Lord of the Northlands, Vanquisher of the pagan hills, Destroyer of the Aberthine Demon was once a great hero in the land. He wielded magic and a sword in powerful combination to drive out the forces of the Outer Darkness. Tempted by the magic of nature, he stole the words from the priests of the Old Gods which would enslave a Fiery Spirit, binding it to Althos’ body. He became the Burning King.
Dabbling in old magics took their toll on King Althos’ mind and, in the end, the Fiery Spirit took over and all but destroyed him. In the end, he fell to St. Garamon the Pious’ sword and was buried in a secret vault, locked away in the Northern Tier of the Rosewood Highlands.
The madness of the Fiery Spirit was such that it possesses the King even in death.
The Sepulcher of the Burning King is a Highlands Location, found at Hex 5A in the Northern Tier Hexcrawl. The Northern Tier is a sub-region of the Highlands. On the larger Rosewood Highlands map this region is just north and west of the city of Newtown, on the border between the Drummond Clan in the east and Great Oaks, the holdings of the Firbolg King, in the west. The Northern Tier covers the northern part of Hex E-4.
The Sepulcher should provide sufficient challenge and reward for a party levels 7-9, with a balanced mix of classes advised. A cleric will be especially useful as a number of undead dwell in the depths of the Sepulcher.
