The Gaping Maw An Eiru Adventure

NOTE: This is a milestone XP adventure! You will level up only when you explore and enter new locations only! This is a slightly slower leveling system but one that fits perfectly in to this campaign and my philosophy of game design and adventure.

Leveling is faster at lower levels - about one character level per dungeon level until 4. Then it is about once every other level from then.

You have traveled to the capital, Dubh Linn, to stay at the legendary Tavern, The Gaping Maw. So named as it contains a portal to the fabled Undermountain. You are ready to write your own destiny and face the perils beneath.

Venture into the depths of Undermountain, a sprawling dungeon filled with ancient magic, treacherous traps, and secrets buried by time itself. As heroes, you will descend into the heart of the Undermountain, facing harrowing challenges, unraveling ancient mysteries, and confronting powerful guardians bound to the Lich, Bodhmall Blackcloak's will.

But beware — nothing in Undermountain is as it seems. Allies may be foes in disguise, and every shadow could conceal a deadly threat.

Gather your party and venture forth.
