📋 About This Mod

A Morrowind Modding Madness 2019 mod by team Dandy Daedra:

- Adds a new sewer system to explore underneath Ebonheart.

- A cast of colourful new NPCs to meet.

- A number of new misc quests suitable for low-level characters.

- Quests with multiple paths, outcomes, and moral choices to make.

- Dynamic environments with traps and secret passages - be careful where you walk, and always be on the lookout!

Compatibility:

Should be compatible with most mods, as most of our changes are in new interiors.

It should be now compatible with Morrowind Rebirth (at least until Rebirth moves Ebonheart walls again).

This is done enabling/disabling things by script according to global short variable dd19rebirth.

If you have MWSE-Lua the mod should auto-detect Rebirth and set the variable, else you will be asked

once at start if you have Rebirth installed, Yes button will set dd19rebirth to 1 = enabled.

Or you can change the settings to 0/1 directly from the in game console, e.g.

set dd19rebirth to 1 (to enable rebirth compatibility)

set dd19rebirthConfig to 0 (to have the config script reset and run again on save and reload)

Note that this does not mean we recommend installing rebirth, as it is currently still full of dirty cells and duplicated objects.

Drop the contents of the zip into your Data Files folder, or (recommended) use your favourite mod manager.
