The Lastwall Campaign
A trio of the High Priests from Razmiran.
The three visions traveled to the isle in search of what was causing the monsters of the lake to attack unprovoked. That was at least what they claimed to be doing there. In truth, the Vision of Fate was there for a more sinister purpose.
At the liches tower his plans were foiled by the party. He was killed there and his partner, the Vision of Shadows was taken prisoner for further questioning.
