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. A band of rag-tag settlers have carved out a small settlement, called Crivdall, on the edges of a great swamp that is infamous for its terrible creatures. The area is rich with resources, and the settlers have done well hunting and foraging in the swamps. Unbeknownst to them, however, an insane druid has taken notice of their transgressions and wants them to leave. The druid, Aleretheral, is a half-orc with a curious affinity for insects and vermin. The swamp is home to numerous breeds of monstrous insects, some of which the druid has begun to breed to make them even larger and more aggressive. Through his abilities, Aleretheral has set enormous vermin onto the helpless settlers, preying on them as they venture into the swamp. With autumn rapidly coming to a close, the settlers are becoming desperate as more of their numbers are killed by hordes of marauding vermin.

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.

“The Temple Between” is an adventure for 9th level characters, and it is challenging enough to take them to 11th level by the time all is said and done. Although intended as the final chapter of the heroic tier portion of the Scales of War Adventure Path, it can be run as a standalone adventure, or as an adventure in a campaign of your own making, with a small degree of modification.
