Give your game’s locations a character all their own! Build encounter themes, emphasize magic places, and connect it all to the monsters living there with Expanded Environments and Additional Actions. Use traits to make creatures stand out and enhance their bond with the land, then add lair actions to reinforce the connection and escalate the fight. New interactions encourage a race between players and monsters to gain the upper hand using the environment around them with additional options in combat. In non-combat encounters, regional effects keep the feel of magic heightened in the surrounding area. Grab characters’ attention, and limbs, in the clutches of fallen armies on the ancient battlefield. Apply library traits and lair actions to a dragon to create an encounter with a bookwyrm. Tempt characters with the allure of enchanted gold in the treasure hoard. Bend fire itself to your will in the heart of a volcano.

The collection started as my own expansion of the environments found in MCDM’s Flee, Mortals! but can be used on its own (along with the existing D&D 5e rules).

This campaign was created as a response to comments from some friends of mine. Though they were avid board game players, they didn’t want to try D&D because it seemed like too much of a time commitment with too many rules to learn before getting started.

I’m putting it online in the hopes that other people can do the same with it and expand the community. Inspired by /u/plaintreality of Reddit.

Goblin attacks have always plagued the farmers and merchants who live and travel along the roads leading to Whitesparrow. But a recent rash of new attacks are something different. The goblins of one particular tribe have gotten particularly smart, attacking with careful tactics and cunning ambushes. The village guards haven’t been able to outwit the goblins, even when laying traps of their own and hiring mercenaries to stop them. Even as goblins go, Rosethorn isn’t much to look at. He’s small and runty, and yet a lucky break placed him in charge of the Brownleaf goblin tribe. When he claimed a powerful magic relic from a dead wizard three months ago, Rosethorn found his intellect multiplied many times over. The world began to make a more intricate kind of sense to him, and he saw patterns in the ways other folk traveled the roads. After hiring a spy in Whitesparrow to tell him which wagons to pursue, Rosethorn cunningly bribed the wagons’ guards to throw battles in the goblins’ favor. He then moved the lair of the Brownleaf tribe away from their dank caves and into the ruins of the Bearded Man—an enormous dead tree at the center of the Howling Wood. There, Rosethorn continues his campaign of ambush against the foolish villagers, increasing his wealth and power with each robbery.
