Legend tells of once-proud fortress that fell into the earth in an age long past. Now known as the Sunless Citadel, its echoing, broken halls are said to house malign creatures and treasures of a long forgotten past.

With the previous inhabitants long dispersed, vile and opportunistic creatures common to lightless dungeons infested the subterranean ruins.

Over the years many adventurous groups have also delved into its dark corridors in the hope of fame and fortune.
Hearing tales of this Citadel you have traveled to the small village, Clan Ros Eó, in the Kingdom of Airgíalla, to learn more and test your mettle against its inhabitants in the search for adventure and riches.

Making good time through the wilderness you arrive in the village in the early morning. Gather your party and venture forth.......

Current Version: 1.7

This campaign was inspired by The Sunless Citadel (2000), a 32-page adventure module for 3rd edition written by Bruce Cordell. It is intended for 1st-level characters. You'll reach level 5 or more by the end.

It is set in my fantasy world of Eiru and updated for 5th edition. I've made many changes to the original - some by my own choice and some due to limitations of the dungeon designer.

- Total of 26 maps
- Multiple different types of environment
- 19 interactive dialogs with NPCs
- Customised monsters, NPCs, and Journals
- Huge volume of optional lore to interact with
- Balanced encounters tested against all builds
- Recommend a mixed party
- Puzzles and mysteries to solve
- Must own the Lost Valley DLC to play it
- About 5-10 hours of play
- Interactive dialog that updates depending on your actions.
- Backgrounds, races, classes and personality flags also change dialogs options

Role Play medium and balanced encounters.

HUGE shout-out and thanks to the play-testers, Flohr and LeleC. Their feedback was invaluable.

Any bugs left are my miss - please let me know if you find anything.
