Efrideet is well known for her strength; she once threw Saladin Forge at a FallenWalker like a javelin. She was long thought to be dead until she returned, and she urges Guardians to participate in the Iron Banner as a way to strengthen their light.
According to the lore tab of the exoticghost shellCosmos Shell, Efrideet was present fighting the Red Legion attack on the last city and "Killed 216 Cabal with 199 bullets". Her fate is unknown, as the last sentence reads "I can't wait to see it. I'm coming home. Efrideet out."
