The Dungeon of the Mountain King

(The Mountain of Time)

The beautiful Mountain of Time was conquered by the Mountain King and his Trolls.
The Mountain King was the apprentice to the Terra Magna. His up and coming nephew. During his mentorship the young man turned evil and tried to rip all the knowledge of training/guiding/molding the land from his uncle all at once. Of course the Terra Magna refused to teach his nephew after that. Of course the nephew grew angry and tried to kill his uncle. Of course the guard was sent after him. The nephew took what knowledge he had and fled.
With his sole skill of working with stone, the nephew hid in the mountains and befriended the Trolls. Then he found that twisting the Gobbet Light through their stone allowed him to control the stone bellied Trolls. They were his. He used them to attack the Valley of Time and chased the Magna's out of their mountain. All of them except the current Aevus Magna, who had seen him coming of course and had taken precautions.
However the Aevus Level was a small one. He didn't figure he needed it. She could rot in her tiny level and he could always lop off that bit of mountain if he needed to. The other levels were more than large enough for his purposes. Setting up Guard Trolls all about the Valley and inside the mountain he gloried in the new headquarters and started bringing in prisoners.
He called himself the Mountain King. Now to gain strength and be rid of his uncle so that he could have power over all the land, not just stone.

Purpose / Function

The four accessible levels with their curious locking mechanisms made for wonderful dungeon levels. The hollow stone Pillar striking through their centre was originally intended to supply the Magnas with fresh Gobbet Light. The Mountain King found, with a bit of tweaking, it could suck the Light out of all his prisoners and transfer it through the Pillar to his quarters in the upper mountain.

Alterations

When the Mountain King first attacked, the Magna's looked into the future and discovered his intention. He didn't want to kill them, specifically. He just wanted to take the Mountain itself. So they placed locks on the sliding stone doors on each level that could only be unlocked by the Magna that it belonged to. Their locks coincided with their own powers. Most of them, if you knew the trick, were abysmally easy.
Aquae Level - dripping sea water into the stone bowl jutting from the door frame allowed access.
Terra Level - drizzling a fine stone dust into the bowl
Ignis Level - lighting a fire in the bowl, of course
Atmos Level - whipping an icy wind through the scoop of the bowl
Aevus Level - stopping time. There was no bowl.

Architecture

Two mountains, one balanced and molded atop the other, point to point. The end result was a massive stone hourglass.
On the broad base of the top mountain that faced the sky was a lush garden with a pool, a waterfall and a vineyard. Unusual for obvious reasons.
The river that crept out from underneath the mountain spiralled around through the valley and eventually spilled into the sea, was freshwater. Unusual so close to the ocean.

History

The Mountain of Time was originally created to give the Magna's a centre of operations where they could all make use of the future telling skills of the Aevus Magna. It was overthrown by the student of the Terra Magna.

Tourism

Really? Tourists? You'd be emprisoned, probably beaten, and sucked dry of Light and life if you tried any sight seeing.

"This Mountain of Time, with every last Magna abiding within, will forever be an unquenchable Light to the nations of the Aerth! Every last one of them."
"I forever hope you are right, though, I see many paths in our future and it is highly probable you are wrong."
~ Ignis Magna Siladock and Aevus Magna Fivora, The Glorious Day of Mountain Tippage

"She said this would happen."
"No she didn't. She said this could happen, not that it would."
"Same thing."
"I wonder if she'll ever get out."
