The Citadel of Kaygys
Also known as the Sunless Citadel
Purpose / Function
Inside, the architecture has been accented by the signs of rudimentary Dwarven habitation, Dragonkin habitation, and Goblins habitation, though the dwarven symbols are decades old, and the Dragonkin and Goblins have lived in the span of centuries, overwriting each other.
At some point, goblins moved into the Citadel, and they and the Dragonkin have been warring over the ruins.
Thirty or so years ago, two adult children of a local merchant's went adventuring into the Citadel with a party of strangers, and died. The dwarves, Ulfgar, and Gurnat, with Ferish the Half-Orc, and Thorn Halfling had gone into the Citadel at her request to recover her children from the ruin. At this time, Oakenfield was plagued by something drinking the blood of their livestock.
A druid was using the dead as bodyguards for his own goals, and was killed as a means to avenge the dead adventurers. As most of the goblins were cleared from the Citadel, the two dwarves decided to inhabit the ruins themselves. Thorn and Ferish parted ways and made for their own historical events.
