You've completed the
The Grand Game, exposed
Ammalia Cassalanter and
Victoro Cassalanter, and were named Wardens of Waterdeep for your service to the city.
Now a new mystery reveals itself: gem dragons are not extinct as the world once thought. A sapphire dragon protected a mysterious shard in
Undermountain until he was killed by Manshoon.
In his dying breath he asked for your help. You descend deep beneath Waterdeep to find the "Heart of the Mountain" and solve the riddle:
"Five to bind. Five to banish. The last will protect the many"
