From the ReadMe:
Hall of Doors v1.5, by theKettle
Tired of the endless walking? Annoyed that even the various forms of instant travel don't reach many settlements? Hall of Doors adds a new area - a small interior cell with 28 doors to various parts of Vvardenfell. Once you've gained access all travel to and from the Hall of Doors is free, via a 'portable door'.
Installation:
Unzip the file to your 'Morrowind' Directory. Run the Morrowind launcher, and select the HallofDoors.esp in the 'Data Files' section.
Finding the Portable Door:
To begin the hunt for the legendary Portable Door, find and read the Journal of Tarhiel (the Icarian Flight guy), on the path north of Seyda Neen.
If for some reason you can't find the journal (for instance you sold it to some random merchant and can't remember who), the following is a transcription of the added paragraph:
"New information has come to light regarding my previous research, the fabled Hall of Doors! I've just heard that the last known owner of a Portable Door was seen in the vicinity of Seyda Neen. She was apparently hunting a rare type of cave-dwelling mollusc and was heading for a place called 'Addamasartus'. I shall make this the destination of my Jump, once all the calculations are finalised."
If you've hunted all through Addamasartus after installing this mod, and still can't find the door, see the spoiler info at the end of this file.
Using the Portable Door:
To use the portable door, you must first drop it on the ground. Move around to look at it, and simply click the 'activate' key (Spacebar by default). This will transport you to the Hall of Doors and return the portable door to your inventory. Currently any companions will, by default, not be transported.
If you drop the portable door, and wish to pick it up again without travelling to the hall of doors, hold down the 'sneak' key and activate the door.
Navigating the Hall of Doors:
The Hall is divided into 4 short corridors - North, South, East and West - each containing 7 doors. I've arranged them to roughly correspond to the areas of the map that the doors send you to.
North: Ald-Ruhn, Maar Gan, Ald Velothi, Khuul, Urshilaku Camp, Ahemmusa Camp, Dagon Fell
South: Vivec (Redoran Canton), Ebonheart, Suran, Mzahnch, Molag Mar, Tel Branora, Azura's Shrine
East: Seyda Neen, Pelagiad, Balmora, Caldera, Hla Oad, Gnaar Mok, Gnisis
West: Zainab Camp, Erabenimsun Camp, Tel Aruhn, Tel Fyr, Tel Mora, Tel Vos, Sadrith Mora
Have Fun!

SPOILER
If you really can't find the Portable Door, here are directions to it:
Enter Addamasartus (the smugglers cave opposite the Seyda Neen silt strider). Go through the first door, and head right down the steps. Keep going straight into the water at the bottom of the steps, and you'll find a little cavern, with a corpse lying next to a sabre underwater. Check the corpse to find the portable door.
