Jesse's World 5th Edition
General: Situated along the edges of one of the four lakes that comprises the Bramblewood Marsh, the sunken tower leans dangerously as if it is just seconds from toppling into the surrounding muck. However, the tower has existed thusly for as long as people can remember, always threatening to collapse but forever remaining upright.
Erected long ago by an unknown wizard, the tower has been abandoned for many years. Its upper levels have been thoroughly picked clean by bands enterprising adventurers and, whether the tower ever had any lower levels, they have long ago sunken beneath the surface of the marsh. Rarely, sages, scholars, and adventurers will venture out, braving the dangers of the marsh and the Witchwood, in search of evidence of the vaults, laboratories, and treasures that surely must be hidden beneath. Most return disappointed (and with a healthy loathing for biting insects…) and some don’t return at all.
Creatures: Though the tower is considered abandoned by many, it has served as the home for the occasional roving bands of goblinoids, orcs, or ogres that come slinking out of the mountains. Most move on to more pleasant locations or disappear within the gullets of the always hungry denizens of the marsh.
