Low voices murmur a dark hymn to an ancient Evil as shadows dance across stones drenched thick with infidelic blood. It is within the walls of the Sanctuary that the Cultist performs his eldritch arcana. The Rituals that are channeled here are black spells filled with vile potency, bought from the Aether through sacrifice, gleaming coin and magic offering. With the power of these unholy sacraments you may wither the will of your enemies, sunder your mana for mountains of gold, or enfirm the rocky walls of your once-vulnerable Dungeon.
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.
