The Arena of Power is a versatile an variable battleground where player characters can fight player characters or groups can fight their enemies. We all know the PvP functions of video games. They may call “battle royal”, “arena” or “rumble”, but it is always a number of players fighting each other until only one is left standing. And the Arena of Power now gives you a place and some rules to do exactly that with your players. Send them into the arena and find out how well they know their skills. The Arena of Power is composed for 2 – 7 players of level 3 – 12.

She ran. Where to or for how long, she really couldn't say. The little flame of her oil lamp sputtered and went out a few times. She'd snap her fingers and make the wick flare to life, but she may as well have ran blind. The hallways were pitch black with soot and choked with smoke, every turn was a guess and every corridor a gamble. Unnatural screams echoed from every direction. Left, right, left again, was this the south or north end of the labyrinth? She had no idea. The next turn brought her face to face with a doorway completely consumed in blue fire. The room beyond was so bright she had to look through her fingers at it. A shadow covered her, a shape in the doorway: a hulking creature with a wolf-shaped muzzle and enormous pincers for hands, wreathed in the same blue flames. The screams were getting closer behind her, too. They had her cornered, again. The demon slammed its shoulders through the narrow opening, splintering the wood and stone. She dropped the lantern and let the wand in her sleeve fall into her waiting hand. With a word of power and a gesture, she appeared in the familiar bedroom: stuffy and reeking of wood smoke. She'd have to try again tomorrow, if she could remember. During an exploration on the sixth level of Undermountain, a strange invisible creature leads to a series of collapsed chambers that hide a forgotten secret and one of the most devastating forces known to the multiverse. Marambra Nyghtsteel, the forgotten apprentice of Halaster Blackcloak, has been locked away for an age deep within Undermountain. What point and purpose her forced seclusion has, only Blackcloak may know. When a spell consuming blue fire, known as The Spellplague is trapped within the chambers, a series of events have left Marambra, lost in her madness, struggling to survive.

An interesting and atypical adventure in its writing style. For one the module contains insightful "When things go Wrong" sections and DM guidance for sticking close enough to the rails for the story and fun's sake. Lots of DM hints about how to handle PCs' choices. Overall the story is fine too - a traditional hook, a mystery, some twists. There's a tower, a surprise pocket-dimension context, and a dungeon. It's mirror of life trapping, isn't it? Well, yes and no. People go in, and they don't come out. Nor can you talk with anyone inside. Somehow, that's not quite the way you remember those mirrors work. This Skarda fellow showed up a few years ago with a band of raiders, and no one in the land has been safe since then. Whole villages have disappeared into this Skarda's mirror. Your band is approached by relatives of one of the victims?and adventurer like yourselves. You have to get into that mirror of whatever-it-is, find this man, and get him out in one piece. The reward is more that adequate. Only problem is, no one out here can tell you what to expect once you get in? or even how to get there. TSR 9188

The carcass of a gigantic sea monster is now a small dungeon... Gargantuel was a gigantic sea monster (a whale? a prehistoric serpent? the Kraken? Leviathan itself?). She used to roam the high seas, destroying ships and devouring everything. Some of the people she swallowed survived in her belly. One of them, the sailor Torsti Seppänen, actually managed to turn the place into a comfortable habitat. One day, Gargantuel passed away. Her body now lies out in the open, luring the carrion-eater, the curious, the foolish. Strange creatures and artifacts await in the mounds of decaying flesh, and the insane Torsti Seppänen will do everything to defend his “home” from intruders. Statted for Lamentations of the Flame Princess, usable with any OSR type game. Hosted by eldritchfields.blogspot.com

A young black dragon and two hatchling dragons live in an excavated sandstone burrow in the swamp west of Knacker Knob. Connected to the dragon lair is a complex of sandstone tunnels and chambers inhabited by lizard men. Some sandstone tunnels and chambers are partially flooded, and others are filled with nasty things such as slimes, oozes and gelatinous cubes. The lizard men revere the dragons as magical spirit guardians. In small groups the lizard men are easily defeated, but if allowed to prepare a common defense, the lizard men tribe with its spellcasters may present serious threat to the player characters (PCs). Wild Dragon Den is the first dragon's lair to conquer. Part of TSR 1073 The Dragon's Den
