Like sand through the hourglass, these are the demonic days of our lives...

 The Clock of Potency (#23/30, #266/365)

"A bizarre sight rises from the flat gritty plains in front of you. An immense hourglass as tall as a mighty tower, made from glass and dark wood, containing glowing purple rock-sized grains of sand, lies propped up, largely vertical, against an outcrop of rusty metal. The tilted base of the hourglass is slightly buried under the outcrop it rests upon, next to a small hamlet of several tattered huts cloaked in thatch, skins and hide. A procession of robed figures form an orderly queue collecting grains of sand from a crack in the lower section of glass, one per participant, and carrying them to the top of the hourglass, where they deposit the grains of purple sand via another crack in the the upper half.

Complicating the process are a flock of leathery winged humanoids perched on the topmost point of the leaning device. Periodically, one of them launches itself into space, arrowing downwards towards the procession, grabbing a robed figure in its talons, and tossing them up into the air for the rest of its foul brood to attack and dismember mid-flight.

Whenever this happens, another robed figure appears from one of the huts and joins the queue to collect a glowing purple grain of sand."

Contents: The sand grains are actually rock-sized chunks of Warpstone, each one worth 20-70GP, but double this to technomancers, Dwarf engineers and the like. Warpstone is thought to cause Chaos Mutations; anyone who handles or carries Warpstone without protective clothing or spells for an extended period of time (2-12 days usually), will develop a Chaos Mutation (see Encyclopedia Arcana: Volume 1, p. 57).

The figures are Demonic Servants who will defend themselves individually if attacked, while the rest will continue carrying the Warpstone to the top of the hourglass. Every time a Demonic Servant is slain, a replacement will appear from one of the huts. This hut contains a one-way portal to the Tower of the Wheel on the Plane of Pain, where new souls to the Pit are assigned their duties.

On top of the hourglass are a colony of Harpies and Gargoyles; they will only attack Heroes who ascend to the summit, but will flee if reduced to half their numbers or less, gliding out over the desert while squawking insults all the while.

The hourglass is a strange and enormous protection device devised by a long-ago crazed Rust Demon called Vth-Lq-Srv the Machine Mage, where the energy generated by the falling grains of Warpstone maintain secure planar boundaries in an area of potentially dangerous dimensional anomalies. However, the energy needs to be generated at a certain pace and amplitude, hence the ridiculously inefficient set-up currently in place. The Machine Mage is believed to have codified their life's work into a grimoire, which has subsequently disappeared along with its author, however, translated snippets and scraps of lore from the original grimoire occasionally appear from time to time, both here in the Pit and on Titan.

If the entire process is disrupted, perhaps by slaying or incapacitating all the Demonic Servants and sealing the portal, then this region will begin experiences planar support issues as follows:

1-2: Incursions from the Plane of Fire. 2-7 Fire Elementals emerge and attack!

3-4: Time loops caused by the cessation of the Clock of Potency. Roll a die: 1-2 Repeat previous day! 3-4 Start current day from morning! 5-6 Start completely new day!

5-6: Incursions from the Plane of Air. 2-7 Air Elementals emerge and attack!

Stats:

200 DEMONIC SERVANTS, SKILL 8 STAMINA 8, Small Claw. If a Demonic Servant is struck twice in succession, the spell animating its body will be broken, and it will collapse back into a pile of mouldering bones.

In the huts, as well as the portal (a rune-inscribed free-standing bronze circle), are a few bits and pieces: 3-18 black robes in a pile, the skull of a Gargoyle, and a forgotten chunk of glowing purple Warpstone worth 50GP

2-12 HARPIES, SKILL 7 STAMINA 6, Small Claw. Can fly.

2-12 GARGOYLES, SKILL 9 STAMINA 10, 2 Attacks, Large Claw, Heavy Armour. Only harmed by magical weapons and also afraid of fire. A normal weapon will break after hitting a Gargoyle twice. Can fly.

On the outermost edge of the hourglass, among piles of stinking guano and bones, can be found 2-12 GP, a Red Jewel worth 25gp, and a glass vial of silvery Rustbane.

FIRE ELEMENTAL, SKILL 14 STAMINA 18, 2 Attacks, Large Claw, Light Armour, +2 to Damage Roll. Only harmed by magical weapons. Two successful strikes on the Elemental will destroy any weapon!

AIR ELEMENTAL, SKILL 15 STAMINA 20, 2 Attacks, Large Claw. Only harmed by magical weapons. Test for luck to withstand raging winds; if lucky, lose 2 STAMINA points but can stay on feet for 2 Attack Rounds before needing to Test for Luck again. If unlucky, lose 1 SKILL and 1-6 STAMINA and knocked to the ground.
