Rebecca

Warning: Major spoilers ahead!

Rebeca is the character played throughout Paraphore. Choices made by the player (you) control what Rebeca inputs as commands to the computer. This becomes more apparent during the PROTOCOL and Mynt endings. She is the daughter of Cade and Wendy and half-sister of Mynt. But since Archbishop was the one who helped Wendy raise her when Cade wouldn't he is considered her father. Rebeca has severe learning disabilities resulting from her total isolation and history of severe hypoxia abuse.

Rebeca is at least 71 years old. This can be found by taking Rebeca's birth year, 2012, and subtracting it from the current year, 2083. The current year can be found on Wendy's desktop during Mynt's second automated message. This is further supported by information given by one of the Paraphore intro/loading screens, in which it is stated to Rebeca that "Your last session was idle for 34,689,693 minutes." This is equal to around 66 years. When combined with the knowledge that the game was used commonly inside the shelter after the Paraphore event, and Rebeca was alive and old enough to have memories from before the Paraphore event, Rebeca should be several years older than 66--making 71 years a reasonable estimate.
