The party is enlisted to assist the Righteous Host, an army formed as a last resort to defend the world against the monsters of Elemental Evil. The host is greatly outnumbered. Its leaders send the party on a series of missions, each of which will give the Righteous Host an edge in the great battle to come. This epic adventure ends with the final push against the forces of Elemental Evil in the Meadows, and the outcome is informed by how effective the party is in their missions... and whether they are willing to risk putting themselves in the front lines. If the Righteous Host loses, players may decide to travel to Hommlet or other nearby towns to defend them. Whether the host is successful or not, players can decide to follow many different plot threads: exploring the Temple of Elemental Evil, finding the lich Kell the Eldest's lair and destroying his phylactory, or following the will of Bitbaern's Shield and discovering historical sites that were previously lost.

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.

Mimic Madness is a psudeo-adventure with four interesting mimic encounters. These four encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL4 to 7.
