Campaign Premise: The Silent Mandate

Sigil is stable only because the Lady of Pain wills it so—but even her control has limits. Across the multiverse, certain realities are unraveling. Portals are destabilizing, timelines collapsing into paradox, planes bleeding into one another. These disruptions form The Fracture, a spreading cosmic fault line that threatens Sigil’s function as the center of all doors. If enough worlds fall out of alignment, Sigil itself could lock shut—or worse, explode outward into infinite catastrophic gateways.

To prevent that catastrophe, the Lady’s dabus have begun issuing rebus-glyph summons to chosen mortals: you. You are not told why you were selected. You are not told what larger purpose you serve. But the summons come, and the doors open, and refusing them is not an option.

Your assignments come from a small, secretive office inside the Hall of Records known simply as The Mandate Desk. A single dabus appears for each briefing, floating its pictogram instructions while a mortal clerk translates them into words you can understand. Each mission drops you into a world, moment, or variant realm where a piece of The Fracture is forming. Your job is simple: Go through the door. Stabilize the anomaly. Retrieve what must be retrieved. Eliminate what must be eliminated. Return alive.

The rewards are substantial. Sigil’s coffers are bottomless, its artifacts unparalleled, and its connections limitless. But beneath the gold, there is the real reason these missions matter: Every stabilized world reinforces the multiversal lattice surrounding Sigil. Every success buys more time before The Fracture reaches the City of Doors. Every mission is another stitch in a cosmic tapestry that is rapidly coming undone.

You are not heroes in the traditional sense—you’re the last line before total planar collapse. You fix the breaks no one else can reach, traveling through dead worlds, unborn futures, alternate timelines, and impossible planes. Each assignment could be anything, anywhere, anywhen.

The multiverse is fraying. Sigil needs operatives who can walk through the doors and do what must be done.

You’re those operatives.

What it is:

• Strike Force: Sigil is Carthanelle’s West Marches campaign. Any member of the server can organize a Strike Force adventure. The adventure can take place in any world, and plane, and at any time. It’s up to the DM and the adventure they want to run. The Mandate Desk will tell you where you’re going, what your mission is, and which door to take to get there. It’s a quick and clean recipe to get characters right into the game. 
• Anyone can roll up a character for the Strike Force. Whether you play or not your character will level along with the group. Play when you want – you won’t fall behind. Progress is server wide.

Leveling

The Strike Force levels at a set rate determined by the number of Fracture Resolutions (missions) that they successfully complete.

Fracture Resolutions Required per Level

How it works (DM’s):

• All you have to do is have an adventure for the Strike Force. No long winded set-ups are needed. The Mandate Desk sends the characters to wherever you want them. All characters are committed to doing their best to solve whatever challenge the Mandate Desk has requested. 
• Post your adventure on the discord and confirm seats as players respond
• Let players know what VTT you are playing on and how to access it

How it works (Players):

• If you want to play a listed game let the DM know. Make sure your character is leveled to the appropriate point. Characters should be created in D&D Beyond. 
• What about loot? In-game loot is distributed as noted above.
• What about loot if I only play occasionally – how will I keep up? All characters have access to the same amount of loot as defined in by the total number of missions that the server has completed.
