Dawn's Light Symbol

The Dawn's Light Symbol is an ancient holy symbol of the deceased solar deity Amaunator, which also doubles as a key. It is part part of the quest to explore the Ruined Temple in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition.

Location
The Dawn's Light Symbol is initially broken into three pieces, which are scattered around the temple's ruins.
 * One piece can be found by completing the three rituals of Amaunator at the Statue of Ritual in the northeast of the dungeon.
 * One piece can be found by returning Amauna's Bones to her tomb.
 * One piece can be found hidden in an alcove in the back of a cell near the defiled chapel.

Purpose
The Dawn's Light Symbol acts as a key to unlock the doors leading to the lair of Thaxll'ssillyia the Shadow Dragon, and beyond her the Shadow Altar and the Shade Lord guarding it.

Completing the Dawn's Light Symbol by finding all three pieces grants the party 21,250 EXP, in addition to EXP gained from completing the associated unmarked side-quests - 45,500 EXP is gained thricefold for interacting with the Statue of Ritual (that is, 45,500 EXP each time that one of the three rituals is completed), and restoring Amauna's Bones to her tomb grants the party 17,750 EXP.
