Oolacile Sanctuary

The  is a location in Dark Souls, but can only be accessed in the AotA DLC.

General Information
The Oolacile Sanctuary is the first location which the player travels through in the Artorias of the Abyss DLC. It is home to the Sanctuary Guardian, who will be encountered after walking though the first fog wall.

It is a relatively small location, as it consists of three main parts: the first bonfire, the boss fight arena and the graveyard before the Royal Wood. The graveyard area has another bonfire, and is also the place in which Elizabeth resides.

Moving through
First Bonfire: This area is very straight-forward, as you can only move forward, until you reach the fog wall.

Boss Arena: This is where the Sanctuary Guardian (and the respawning Lesser Sanctuary Guardians) can be fought. It is a very large and circular area, with a thin layer of water on the ground.

Graveyard: After defeating the Sanctuary Guardian, this area will become available. A second bonfire is located very close to the entrance. A Humanity can be found if the player turns right at the bonfire, on a corpse behind a gravestone. Elizabeth is found to the left of the bonfire.
