Tymarell was a rich city-state, located at the headwaters of the Panthera River in modern-day Rakore. Tymarell was founded in 305 Avard, and reached its peak just before it was destroyed by a pyroclastic flow in 612 Avard. A long-dormant volcano known as Mount Weltdown was active just long enough to destroy Tymarell, before going quiescent once again.
Tymarell excelled at gold-mining and smelting, and was also known for its fine wools and woolen tapestries. The city-state was ruled over by a duke, who was appointed and supported by a council of the most powerful and influential members of the land. One member of the council was a powerful priest of Mikindim, whose church constructed the vast underground sewers of the realm. Other members of the council included a wizard of considerable skill, a silver dragon, and a representative of the local dwarves, the Deepsmiths.
The awakening of Mount Weltdown was met with some concern, but it was not considered a great threat to Tymarell. The pyroclastic flow befell the city so quickly that nearly everyone died instantly. Killishandrastatia, the silver dragon that influenced the city-state, died horribly of asphyxiation after his lungs were burned out by the flow; unfortunately, his death throes collapsed several of the underground sewers that had survived the flow intact. The sewers are currently a confusing maze of tunels and labyrinthine corridors, made more confusing by the incursions of the Deepsmiths after the city had fallen.
Some of the sewers came up underneath buildings of considerable importance within the old city-state, in include the city treasury, the wizard's tower, Killashandrastatia's home, the city armory, and the homes of several residents. Killashandrastatia's home contains a hint as to the location of his treasure horde, in the form of a cryptic map set in the floor to his study, hidden in the mosaic tiles.
A number of creatures have moved into the tunnels, over the years. A few of the old buildings poke up from beneath the stone-formed ashes, allowing various entrances and exits, especially as how many of the buildings were broken into from below, by either the Deepsmiths or various creatures. The Deepsmiths, for their part, tried to access the treasury, only to be turned back by the earth elemental the wizard had emplaced. Most of the Deepsmiths were wiped out by the humans of Stomalin some time later.
The former ruler of the underground was Grythe, a powerful troll that lorded it over several Deepsmith slaves, and an otyugh. Grythe was defeated by a small group of Gideon Enterprises operatives, though they withdrew afterwards, having suffered heavy casualties. Two of their bodies lie rotting in the sewers where they died, half-eaten by rats, and cut in half by the greataxe Grythe had wielded. The troll is still regenerating, and it might be several years before he is able to lord it over the Deepsmiths, again. He hides, deep within the sewers, patiently healing from his terrible wounds.
Other, lesser creatures currently inhabit the tunnels, as well, including rats, a giant constrictor snake, monstrous spiders, and even a will-o'-the-wisp.
A ring of earth elemental control is needed to bypass the summoning ward on the treasury; without it, whole armies could be ground to pieces. The ring was taken by rats deeper into the maze of tunnels. Detect magic or similar spells might be used to help find it. As well, a skeleton lies beneath the pipe the rats took the ring down -- the poor fellow was eaten alive by rats, while he tried to get at the ring.
The treasury contained 80 bars of gold bullion (valued at 100 gp each), 24,600 square, golden coins, 13,214 square silver coins, and 3,211 square platinum coins. It was cleaned out by operatives of Duke Herod Notimeh, in order to finance his operations that hinder Rakore. Closer observers will note a substantial change in the economy of Rakore, with Duke Notimeh's operatives claiming to have 'found' the treasure in an ancient city across the seas in Baroneth. Although all the gold is gone, the earth elemental contained within its permanent summoning circle still defends the front entrance -- though the back has a mine shaft punched through it from somewhere else in the ruins.
