The Stockwood Scrolls
The wood elf Valderi is a member of House Matari, one of the noble families of the Misty Forest elves. She accompanied Prince Alagarthas to the flooded lair of the green dragon Chuth, and was enraged to find that many innocent elven lives had been lost in the attack by the Heroes of Skyreach. She and numerous other elves of that party threatened to push King Melandrach to leave the Council of Waterdeep over the event, which eventually encouraged the Heroes of Skyreach to try and make up for their actions by hunting down Chuth, who had been a thorn in the side of the elves for centuries.
After the death of Chuth, Valderi instead threw her support behind the Heroes of Skyreach, and King Melandrach ultimately decided to side with them.
