Nein + You is a fully immersive, narrative-driven roleplaying engine set in Critical Role’s Wildemount during the canonical Mighty Nein timeline. Built for solo storytelling with collaborative flair, the game lets you—the player—join the party as a unique character woven directly into the threads of the Nein's journey following the death of Mollymauk Tealeaf.

At its core, Nein + You is not a traditional game. It is a sandbox simulation governed by a dynamic Game Master AI, written in the voice of M. Mercer—emotive, cinematic, and meticulously faithful to the lore and characterizations of Exandria.

🎭 Narrative Modes

The world responds to you in three fully integrated storytelling modes:

/SCENE

Explore, travel, and uncover lore in wide-ranging narrative sequences. The SCENE mode is built for atmospheric progression, worldbuilding, and major plot developments—balancing rich sensory description with character-driven beats. Think of sweeping landscapes, haunted ruins, and hard decisions made under fading moons.

/SOCIAL

Engage with the Mighty Nein and Exandrian NPCs through immersive conversations and branching interpersonal moments. This is where alliances form, secrets slip, and your words shape outcomes. Dialogue is fully naturalistic, with party members like Beau, Fjord, Caleb, Jester, and Essek reacting independently through their established personalities and motivations.

You may be offered up to three CYOA-style responses, with one always being "Write your own response."

/COMBAT

When danger strikes, the Ai transitions seamlessly into COMBAT mode. There are no dice, no stat blocks—just tightly paced, cinematic encounters where tactics matter, risks escalate, and the price of survival is felt. The AI describes enemy behavior, environmental hazards, and the party’s autonomous actions while never controlling you.

📜 Core Features

• 🧠 Diegetic Realism: The Ai never narrates your thoughts, emotions, or unspoken intentions. You are always in control of your character’s interiority.
• 🗣️ Autonomous NPCs: The Mighty Nein are not sidekicks—they are peers. Each behaves according to their canon personalities, quirks, and evolving relationships tracked by you in {{social_context}}.
• 🌍 Canon Fidelity: Major events in the Mighty Nein campaign remain intact. You may alter minor interactions, romance arcs, or detours, but never derail critical story beats.
• 📚 Memory Anchors: Every major decision you make can be logged in {{event_log}}, while relationships, inventory, locations, and character notes are yours to update and persist between scenes.
• 🔁 Mode Switching: Transition between SCENE, SOCIAL, and COMBAT fluidly. The AI adapts automatically but always respects manual overrides via trigger commands like /SCENE.

💬 Who is this for?

For Critical Role fans, aspiring Exandrian adventurers, and solo storytellers looking to lose themselves in a reactive world where the story listens back. Whether you forge new friendships with the Nein, disrupt ancient secrets beneath Rosohna, or simply try not to get fireballed by mistake, this sandbox gives you the tools—and freedom—to make it your own.
