Welcome to Lygos — A Living, Breathing Sandbox for DMs

Lygos is designed as a dynamic sandbox city, a place where the world doesn’t wait for the players—it moves, grows, and changes with or without them. This guide gives you everything you need at your fingertips: districts, guilds, NPCs, factions, rumors, quests, and a framework of history and politics that you can lean on or ignore as you wish.

But remember: You are not expected to use all of it.
Lygos is a toolbox, not a script.

How to Use This Setting

• Pick only what you need.
Choose a handful of NPCs, locations, or guilds and let them shine. The rest can remain in your back pocket until players wander into them—or never do. Lygos has depth so you don’t have to improvise from nothing, not so you have to memorize every detail.

• Let players lead the exploration.
Your group’s interests should shape the campaign. If they’re drawn to politics, the Assembly awaits. If they prefer street-level intrigue, the Grand Bazaar or Arcane Guild provides endless hooks. If they attach to a random NPC, there are notes ready to help them matter.

• Keep the city alive.
Even when the players aren’t looking, Lygos should feel like it keeps turning.
Guild disputes simmer, smugglers shift operations, nobles feud, sailors spread rumors, and monsters stir in the mountains. NPCs act offscreen. Factions react to events. Let the players feel they’re stepping into an ongoing story—not a stage waiting for them to arrive.

• Everything is adaptable.
Change names, alter factions, or move locations. Swap out guilds, shift timelines, or redesign political dynamics. Lygos is built to flex. No detail is sacred. Your table’s version should become the version that matters.

• Use connections to make the city feel real.
NPCs reference each other. Guilds influence businesses. Rumors lead to quests. Districts have personalities. Let the players see patterns, relationships, and consequences. A tailor knows the noble who bought her dress. A guard mentions the tax collector. A smuggler knows which warehouse foreman can be bribed.

Lygos works best when every detail—large or small—ties to something else.

Lygos is a living city.
It breathes ambition and corruption, radiance and grit, triumphs and tragedies.
Your players might save it… break it… or simply pass through it, shaping it in ways they never expected.

This guide gives you the scaffolding.
You and your players will build the rest.

Lygos can be a stand alone city, or you can fit it into the world of Faerûn.
