The Age of Worms
The once-great Giant city where the society of Stone Giants, allies of the Order of the Storm. lived and ruled for centuries, guarding the phylactery of Dragotha from the agents of Kyuss. Those Stone Giants have long since died out. As generations and centuries passed, their mission of guarding the phylactery vault went from duty to order to tradition, and from tradition to faith and superstition. Then other giants came to Kongen-Thulnir, some on errands of peace, some to make war. Control of the city changed hands countless times. Wars and squabbling reduced the city to ruins, a shadow of its once-mighty glory. Yet through it all, the wards and mystical auras left behind by Saellas and her sisters persisted. Each new tribe of giants to claim Kongen-Thulnir quickly came to view the Citadel of Weeping Dragons as their responsibility. They knew not why. They knew not what rested within the inner vault of the citadel, yet they knew it was their duty to protect it.
Once a beacon of knolwedge, goodness and order, now it is a horror show of foul lesser giants, ogres, and ogre-kin. It is a place of savagery and physical power – not the beacon of knowledge and goodness and order it once was. In addition to the fortress that is the citadel, there is a tower and a palace, as well as an Undercity of slaves. There are anti-dragon paraphernalia strung high above the cavern floor. When the party arrived there on the 12th of Reaping, CY 601, the entire place was under attack by dragons, presumably at the behest of Dragotha, in search of the phylactery.
