5E Adventure: Old School Adventures- #1 Ruins of the Twilight Marches (Color McAusland cover) Old School Adventures is Goodman Games’ new line of hardcover 5E campaigns — each volume a complete, self-contained adventure packed with everything a GM needs to run the campaign of a lifetime. Old-school atmosphere, modern playability. Shattered by a meteor strike, the greatest dwarfhold in Aereth fell and tore a rift into the Shadow Realm. Now bandits, kobolds, undead dwarves, and worse haunt the ruins — and something waits on the other side of that portal. Old School Adventures #1: Ruins of the Twilight Marches is a complete 160-page 5E dungeon crawl across five chapters, taking characters from level 1 to 5. Compatible with both 2014 and 2024 core rulebooks. Everything the GM needs in one hardcover tome.
