From publisher blurb:
The Ruins of Arlast is a 5E adventure module designed with the 5th edition SRD for new players or starting characters. It is specifically designed to make use of two sets of terrain made by Dwarven Forge in four different configurations. Each configuration also has an accompanying Dwarven Forge product that can be optionally used to supplement that dungeon. While having the Dwarven Forge terrain is not required it will add significantly to your game experience.
Core Dwarven Forge Products:
Deluxe Starter Set - Zultar’s Gameroom (Encounter 1)
Classic Dungeon Remastered Core Set
Optional Dwarven Forge Products:
Kobold Tribe
Furnishing Pack
Texture Patches Variety Pack and Mimic Pack

This module is laid out with an introduction, four small ruins to explore and a conclusion. Both the introduction and conclusion take place in the village of Crystal Plains and provide set up and wrap up for the adventure. The four ruins are each their own small dungeon with an overarching story.
