Lore:Guardian Directives
From Destinypedia, the Destiny wiki
Guardian Directives is a Lore book introduced in Lightfall. Entries are unlocked upon reaching Guardian Rank 8 for the first time. It explains what the Guardian can do to face more dangerous threats lurking in the Sol System via raids and dungeons.
I. Raids and Dungeons
As they grow into their power and skills, Guardians often find themselves in need of a 3challenge. Should you wish to take your adventures to the next level, treacherous dungeons and powerful foes are the perfect way to test your mettle.
A well-equipped fireteam of three may face difficult combatants and precarious environments as they make their way through a dungeon. Should they wish for an ever bigger challenge, a fireteam of six Guardians can work together to take on Sol’s biggest threats in a raid.
