. In summary:

• Green Emperor Way is the central district around the White-Gold Tower in the Imperial City.
• It contains the tomb of Prince Camarril, key to progressing the main quest.
• To activate the tomb, visit it at midday after reading the Mythic Dawn books, which reveals the location of the Dagon Shrine
