The Summoning Pits is a Hive ritual ground located deep within the Hellmouth. Here Phogoth, the Untamed is chained to the floor until a team of Guardians challenges him in a strike following the orders of Ikora Rey. Later the Guardian battles there his Nightmare.
In the back of the chamber, on the upper platform, the remains of Guren, Ghost of Toland, the Shattered can be found.
