This tower is said to be as old as time itself. It is also said to be sentient, ready to challenge any group that passes through its doors to determine if they are worthy. While brute strength is enough for some floors, others require a bit more elegance and cleverness, so a diversity is as much a strength as anything else.

While not every challenge is met for every level it is up to the PCs to decide if they are up for the challenge they discover.

It can also be used in an area frequented by the PC party that can offer an increased challenge with each visit they make.

The Approaching Swarm is a short adventure for four 9th-level characters. The party can consist of any mix of classes, but it should include at least one character that is good in wilderness settings, such as a druid, ranger, or barbarian, and at least one cleric. This scenario should prove a reasonable challenge for characters from 8th to 10th level. The adventure takes place in a swampland that is near a small settlement. The adventurers have located the secret lair of Aleretheral, an insane half-orc druid with mastery over vermin. He has been breeding and training monstrous vermin to defend his territory. With the adventurers invading his home, he will do anything he can to protect it.

Base of Operations is a short adventure intended for four 5th-level characters. DMs can easily modify the adventure to suit higher- or lower-level adventurers, or larger or smaller parties of adventurers. Simply adding a few monsters to every encounter area makes the adventure more challenging for larger parties, and adding levels to any of the humanoids can make them more of a threat to high-level groups. For low-level adventurers, make the relationship between the two factions within Brightstone Keep more strained, and take away a few monsters from each group. You can remove levels from some of the humanoids in the adventure to make it a lower-level challenge, but it is important that the orc cleric (described in encounter area 8) still have the ability to animate the dead. Still, he can have fewer minions around him when encountered, and that makes him less of a challenge for a lowlevel party.

About a year ago, an adventuring party found themselves encumbered with more treasure than they knew what to do with. After brief deliberation, the group buried their hoard in a remote grotto inhabited by water birds. It was only a matter of time until one of the resident scavengers exhumed a most unfortunate item.

The ambitious fowl quickly advanced as a mage, and set her sights on conquest of the surrounding areas.

All you have to do is find this mysterious mountain. Unfurl the sails! The open sea awaits you and your crew as you sail from the city harbor. But beware! The Sea of Dread has more than earned its title over the centuries. Can you survive the perils of the sea? Will your crew mutiny before you reach the Burning Mountain? Or will you have to throw crew-members overboard just to make room for the gold? Solo adventure. "Lathan's Gold" is a real innovation in solo adventure design, considerably more complex than any of the gamebooks then being produced. Though the adventures uses the typical trope of numbered paragraphs, its paragraphs are divided into six types: "S"pecularum, "U"rban", Island "E"xploration", "C"oastal", "T"rade Routes, and "V"oyages. Players can jump between the sections, then return, in slightly freeform ways. Players are also required to keep track of hit points, money, and treasure (which were typical for the more advanced gamebooks), and rations, days remaining, and hull points (which were not). Another freeform element, quite unusual for gamebooks, is the "wandering monsters" table, which introduces semi-random encounters. TSR 9082
