Byscilla's Plan

This is an Act 7 main quest, offered by Byscilla, Matron of Rifts after completing the In Service of Bysmiel quest.

Byscilla has used the items brought to her to craft a Gargan Key. It is to be used to summon an ancient guardian that will aid in the battle against the servants of Korvaak.

Objectives

 * Obtain the Gargan Key
 * Eliminate the guardians at the Temple of Ateph
 * Activate the Altar of Ateph
 * Return to Byscilla at the Vanguard of the Three

Guide
The entrance to the Temple of Ateph is found north-east of the Vanguard of the Three. The Altar of Ateph is on the second level. Defeat the three Temple Guardian Bosses before activating the Altar - a Spawn of Ateph gargoyle will appear. Return to Byscilla to complete the quest.

Rewards
Byscilla will then offer the Tomb of the Eldritch Sun quest.

The Spawn of Ateph can be found later in the Remnants of Korvan City, fighting alongside members of the Cult of Bysmiel.
