- Jack-of-All-Trades: John has dabbled in acting, arts, and athletics. Strong suits are classical acting (with his break-out role in Riven) and marathon running.
- Shakespearian Actors: John is implied to be one, having traveled with the Royal Shakespeare Company, for a production of Sherlock Holmes. Directed by Frank Dunlop, with artistic director Trevor Nunn. This provided Keston his sole Broadway credit for his performance as Sir Edward Leighton.
After the first game Myst, the player character returns to Atrus to be inserted into Riven. He/she is given a fake linking-book that appears to be a way back to D'ni, but is actually a one-man prison; to make a long story short, Atrus' wife Cathrine has become a hostage in Riven, being held prisoner by his scheming father.
After solving key puzzles in Riven, the player comes face-to-face with Gehn, who cleverly accepts that he has been in the wrong in order to garner sympathy. However, Gehn is more that willing to commit murder, and will shoot the player dead if they mess up trying to lure Gehn into the trap. Thus, to get the best ending, the major puzzles must be solved.
