Garde are from Lorien in possession of Legacies which they were supposed to use to defend Lorien. Every Garde is designated a Cêpan, a parent-like figure who acts like a guardian towards them. They were trained by Cêpan to fight, because of the prophecy of the end of Lorien. Nine of the most powerful Garde, known as Elders, were in control of the planet. The Garde were gifted with Legacies by the spirit of Lorien, which is known by "the Entity" and "Legacy". All Loric Garde have a variety of Legacies as well as enhanced speed, strength, senses, reflexes, and durability.
After the Mogadorian attack on Lorien, nine Loric Garde children (excluding Ella) were sent to Earth with their Cêpan. All of the Elders are presumed dead. The Garde were hunted down by the Mogadorians about a decade after they reached Earth. Now there are only six (known) Garde remaining.
Numbers One through Nine were in possession of Inheritances, in Loric Chests.
Loric are now no longer the only Garde. A Mogadorian named Adamus Sutekh was gifted with Legacies by Number One. And now, humans are gaining Legacies since Legacy spread through Earth, including Sam Goode, and Daniela Morales, and many other Human Garde.
