The Future Troll Queen
by AozI thought the Old Queenstructure was on the island surrounded by Troll Lake.
Here is my addon feel free to use what you want.
I recall there being a slime covered throne. If the ruins were rebuilt around 1018 AC to 1022 AC by Zoa Kram along with the mining city of Tholl Votar is formed below the island on the East to South-Eastern of Trollhattan (from Micky's Thread).
The important date is 1190 AC- 1200 AC when everything is flooded.
Even after flooding the future Troll Queen had to battle a Copper looking Dragon named Cybrikain (Maze in Dragon) that claimed the Palace just before her. Cybrikain even had appears to be a undead Zoa Kram serving next to him. (In truth, just a look alike undead and the Dragon is Kram [A.k.a. Markvo])
Cybrikain and the future Troll Queen will clash in a few battle as she builds her horde from 1200 AC - 1208 AC. The Dragon's undead loot everything from Tholl Vator to the underwater Shadow Elven Cities.
In 1209 AC, the Future Queen will lead her horde and destroy a small number of about 200 skeletons; however, will find the Palace empty, Cybrikain gone, the undead Zoa Kram missing, all the undead and treasure already taken away.
All that remains is the old Queens Throne. The trolls name Shadrala (Troll Name Generator) as the New Troll Queen. Later that night, 1209 AC, Shadrala thinking about everything that was taken from her goes into a fit of rage and beats on the Old Throne. The Throne moves a tiny bit. With a lot of effort, she is able to move the Throne revealing a small Hidden vault of the Old Troll Queen. A voice calls out to Shadrala, she steps into the vault, then emerges with a trident in her hands, a crown on her head and a vile grin on her face.
