The table within the Sanctuary has seen more death than all but the greatest generals. Upon its sleek surface your Cultists will call to their dark God and perform the sacrifices necessary to please the Nameless One. Once successful you will have the power to cast devastating rituals that affect all opposition within the Underworld or grant a powerful boon to empower your own side.
The Sanctuary is one of the core rooms of the Vein of Sloth.
Your Cultist may now pray to a dark altar which will passively grant you increased mana regeneration. Additionally your Cultist may offer themselves up as sacrifice upon becoming worthy offerings to be reborn again as the Archon, Reaper, or Eternal - powerful mages with devastating arcane powers.
