Ace

"I'm coming home Ace."

- Cayde-6

Ace is the nickname Cayde-6 gave to his son before he was an Exo. It is mentioned that Cayde remembered nothing about him and only knows him by Ace. Once his gambling took over Cayde threw his life away, and that his only means of escape was to sell himself to Clovis Bray's Exo program. Unable to contact his family, Cayde kept a journal which he addressed to Ace. Cayde also named his prized hand cannon, Ace of Spades after him.
