Description
''Far below Castle Nathria lies the Sanguine Depths, a prison created to house Sire Denathrius's most intriguing dissidents. Prisoners here are kept for eons, drained of their anima for research and study. The Sinfall resistance knows of a particular prisoner here that could help tip the balance of their fight with Sire Denathrius to their favor, and have asked for assistance in extracting them.''
