Tomb of Thamas the Demented

Thamas the Demented was buried in a Tomb on Yacg'harr Island.
The land around it has become known as the Barrow Area.
Some scholars such as Silas know of his history, but to all other dwellers on the Island Thamas is know only as 'The Evil King'.
Inside the tomb was a very complex portal that could teleport the users all over Faerune.
The Portal
Here is recorded what is known about the portal system so far:
Construction
There are six pillars in two rows of three inside the tomb, thus:
1 2 3
4 5 6
Operation
A key that was obtained from the Nameless Monastery may be used to 'set' the first pillar to one of five settings.
or something...
When the key goes in, the barrow 'powers up' with a thunder and lightning storm that lasts 2 to 5 minutes.
The symbols then glow blue.
The selected symbol glows brighter than the others.
Once something (like a finger) is poked through, it won't come back again, unless everything else follows.
The portal selected then remains open for 10 minutes then closes.
Portals can be opened again from the far side though.
..
There was also a portal beside us, glowing blue between two pillars that were similair in construction to those in the barrow. The symbol of the chest was replaced with that of a small hill. (? so it was always a barrow?)
