Briarwoods

The Briarwoods are a noble family from Wildmount. They are responsible for the deaths of Percy's family members, the de Rolos.

Background
The Briarwoods were guests of the de Rolo household. During a feast that was held in their honor, the Briarwoods party suddenly and violently took control of the castle, killing or capturing anyone that opposed them. Percy was imprisoned beneath the Whitestone dungeons. He was later rescued by his younger sister, Cassandra, and the two fled. The Briarwoods either were alerted during the escape or quickly found out, as their men chased down Percy and Cassandra. While Percy escaped, his sister was hit by several arrows and collapsed. It is still unknown whether she survived or not.

News from the North
During a meeting with the Tal'Dorei council, Percy discovered from Sovereign Uriel Tal'Dorei III that the Briarwoods recently visited Emon to open communications and establish an official trade route to the northeast. Seeming to be interested in dealing with Tal'Dorei politically, the Briarwoods decided to join with Tal'Dorei, and expand its border to Whitestone. According to the Sovereign, the Briarwoods inherited the region from the de Rolos, rebuilding Whitestone and honoring the de Rolo family's deaths.

Based off of this information, it seemed that the Briarwoods were able to fabricate some kind of story to convince everyone outside of Whitestone that they were not involved in the deaths of the de Rolos.

Percy was able to convince the Sovereign that he was interested in meeting with the Briarwoods when they next visited, and would like to be notified in secret.

Visit to Emon
The Briarwoods visited Emon to finalize plans to build a bridge connecting Tal'Dorei to their lands to establish a trade route.

Whitestone
The Briarwoods had promoted their followers, those that had helped them defeat the former rulers, to nobility. They themselves lived in the castle. They had not been idle for the intervening years, but had built an altar for their "Lord". Furthermore they had imprisoned Percy's younger sister.
