A fallen and desecrated temple of Pelor, recently re-consecrated by Lewin and also 'blessed' with a zone of truth, was found in a chamber 2 miles into the tunnel. Lewin has vowed to return the Temple to its original location in the sun, where ever that actually is.
Around a mile further on from the temple of Pelor the group was forced to take a long winding stair down at a seal that blocked the tunnel (which has since been opened) . Just beyond this seal is the only other room of note in the huge tunnel. The room (that branches off of the tunnel to the left) is a vast stable with windows overlooking the strange 'world' now contained within the mountain. The stable would easily accommodate 100 horses.
Of the world contained within the mountain little is known, except it took one hour to climb down to it, four hours to cross it, an hour to climb back up to the level of the main tunnel. Halfway across you encountered a strange crystal which the moon fairy Sacrifice used to transform the 'world' into an exotic 'moonlight' forest of strange mushrooms and other odd plants. Wimi believed that ley lines run across this cavern and intersect with the crystal. The night spent with the crystal affected everyone to some degree, but some were more affected than others......
The climb back up out of the other side of the cavern lead to a complex of rooms including the 'Elven Gate Room'. The rooms are all on one level about 2/3 rds of the way up wall of the cavern (an analogy is that of a small town built 2/3 rds of the way up a cliff face).
The initial room found was a simple teleportation room (that granted access to the 'Eye of the World' chamber at the summit of the mountain - see later). A door exits the other side of the teleport room granting access to the complex itself.
Exiting the teleport room - To the left are 20 residential apartments, each of which are opulently appointed and unique. Balconies look out over the exotic world below, the apartments lighting temperature etc conform to you wishes. (essentially design your own apartment).
To the right are - several functional rooms.
1) A Library, Occupied by a ghostly mage who has been commanded to rebuild his library by Reagor. Copies of two books are available. A Tome of Dragon Lore and the Horse Lord' Alchemy Book. Only the original owners are allowed to access the copies of these books.
2) An Alchemy Lab - Superbly equipped and with many formulae depicted on the walls. The room grants a +5 bonus to Alchemy work done within it.
3) The Golem Room - Here the Brass Golem was completed by Reagor, with Tiamor and Lewin's assistance. The room has all the equipment required for designing and crafting magic devices, weapons, armour and shields.The room grants a +5 bonus to work done within it.
4) A Ki Meditation Room - In this room heightened Ki Powers may be sought by the initiated.
5) A Healers Room - With the restoration of the 'herb garden' by the Moon Fairies, 'The Healers Room' becomes a pleasant and fragrant place, granting a +5 circumstance bonus to healing checks carried out within it. There are 10 beds within this room.
Straight on - Finally the corridor straight ahead of the teleport room eventually curves around to join up with the 'Elven Gate Room'. Here Reagor and Lewin's Brass Golem now stands guard over the great 'Eleven Gate', and a magnificent pipe organ able to command the nearby landscape with its music, stands ready to be played. The 'Elven Gate' functions (or not) as the DM requires it to for their own particular game. In General the 'Elven Gate' puts you down 2d12 hours journey away from your intended destination (assuming a movement speed of 3mph) - the Gate has become slightly erratic since being struck by Gerard. The group must return to the point where the 'Elven Gate', deposited them and 're-summon' it in order to get back to the mountain.
And Finally - The Eye of the World Chamber - A room at the mountains peak, reached only via the teleportation room houses a huge immovable 'Crystal Ball' with many powers. The only person with sufficient skill to use the Crystal Ball, so far, has been Tiamor (5 ranks of Scrying minimum are required). The room itself commands unobstructed views of the ocean and surrounding lands.
