The Ayleid spirit warned me that if we destroy the Lightless Remnant, we’ll unleash the blood-curse throughout the land…”
There will be a time when Verandis needs your assistance to protect him while he tries to free Gwendis. In order to free Gwendis you need to destroy the Ayleid Stone Guardians. You can kill the guardians directly. You will be attacked by a wave of skeletons and another of Gargoyles until the statues are defeated.
During the Gargoyle wave, lead it around the room to each of the statues. When the Gargoyle does it’s heavy attack, it will destroy the statues. Once all of the statues are destroyed. The quest line continues to the next part.
