Cirdan's full story is incredibly interesting, and he's floating near the fringes of all the Great Stories too. We'll be seeing a lot more of him after I pitch my Cirdan spin-off miniseries. It's set at the beginning of the Third Age right after Numenor has sunk and the world has been made round. Ulmo recruits Cirdan as a Special Secret Intelligence Scout to uncover and foil the evil plots of Sauron's allies. He has to travel the world armed with the ultimate multi-tool Narya, a miniaturized automatic crossbow, and any other magical objects he might need in a tight pinch. Along the way he drinks a lot of wine, woos the lady-elves with his charm and salt-and-pepper elf-beard, and crashes expensive horses equipped with ejection saddles. Currently planned episodes include Corsairo Royale, From Rhudaur With Love, Goldringer, Silmarils Are Forever, License to Burgle, The Wold Is Not Enough, and of course, Dr. Nowë. Frankly, I think Sean Connery could really pull it off.
Just let me know when you want me to start drafting the spin-off outline.
