24 missions in four acts: The Service, The Rifts, The Pattern, The Door. A cell of cadets starts at the House by the Reservoir and goes on to the night in which it is decided what becomes of O.D.I.N. There is no fixed ending. The GM records the cell's choices in a Decision Book and runs three pointers of twelve fields each.

White dice come from the attribute and succeed on 5 or 6. Coloured dice come from the skill and succeed on 4, 5 or 6.

Contents

• 25 GM journals: the introduction with the parties, pointers and Decision Book, and one for each of the 24 missions, from "The House by the Reservoir" to "The Night".

• 28 handouts from "The Door: Handouts", one journal per mission.

• 21 scenes from the player versions of the Map Room, with measured scale, from the Rotterdam tower block and the ballroom on the Ringstraße to the mountain village in Tyrol. The GM versions sit in the GM journals only.

• 4 ready agents from the starter adventure: Raven, Brandt, Echo and Folio.

• 23 enemies with values, dice pools, portrait and token.

What is missing

Five missions (7, 9, 15, 20 and 21) have no map, and mission 16 has one for only part of it. The book gives no start positions; the tokens lie next to the maps and the GM places them. Minor figures without values in the book have none here either.

Requirement

The O.D.I.N. ruleset in Realm VTT. The first mission is included in full, so the starter adventure is not needed as well. The German version is O.D.I.N. Die Tür: Kampagne.

The book

"The Door: Campaign" and "The Door: Handouts" are free PDFs: https://odin-rpg.pages.dev/en/book/the-door. The book is for GMs only, assumes the Game Master's Book and recommends a session zero before the start.
