Celestial Paths

Exploration Stage: Polar Quarter
From: Yui
Description: Serving the Blue Dragon is not an easy task, but I intend to take on this challenge with dignity. Because as sisters, we should help each other. Next we need to find out when the vernal equinox is. For that, we need the Amirali Celestial Globe. Can you help me find it?
Completed: Thank you. You brought me this fragile ancient device without a scratch on it. Now, take care of it and hand it over here. Now I'll be able to determine the date of the vernal equinox and tell Seiryuu about it. This is important information for Seiryu, the king of the heavenly realm.
