Lore:A New Age
From Destinypedia, the Destiny wiki
A New Age is a Lore book introduced in Lightfall. Entries are unlocked upon reaching Guardian Rank 7 for the first time. It explains the Guardian's interaction with the Tower, as wells the in-game holidays celebrated there.
I. The Tower
As every Guardian knows, there are few dull moments in Sol, but any precious downtime is most often spent in the hangers and hallways in the Tower. Operating as a base of operations for the Vanguard, the Tower overlooks the Last City and the Traveler, serving as a watchful eye should any threats arise.
As the seasons change, so, too, does the Tower. Guardians looking to partake in holiday events and festivals like, Guardian Games, Solstice, Festival of the Lost, and the Dawning, will find Eva Levante leading the celebrations with special activities and decorations galore!
