Lost Cities Keeper Wiki

Quinlin Sonden works in Atlantis, running an office as the Chief Mentalist, and is known to be one of the strongest Telepaths alive. His office is on the farthest side of Atlantis, which is out of the way to keep prying eyes (especially the Council) away from his work. He is the Telepath that performed the memory break on Prentice with Alden as his guide. Quinlin works closely with Alden looking into suspicious things having to do with the Forbidden Cities, and assisted him in searching for Sophie for 12 years. Councillor Bronte does not trust Quinlin and gave him a receptionist that spies on his work. Quinlin is married to Livvy, although he wants her to file a match fail, the Elvin equivalent of a divorce.


Quinlin is a tall elf. He has dark skin, shoulder length hair, and sharp features. Sophie describes him as, "Insanely handsome, but everything about him seemed serious." He was Alden's Cognate before they made the mind break on Prentice.


Alden is a very close friend of Quinlin and the two have worked closely together to find Sophie without the Council's knowledge. In Neverseen, it was revealed that Quinlin and Alden were Cognates. However, because of a loss of trust after Prentice's memory break, this is no longer so.

Livvy and Quinlin have been married for nineteen years. They fight regularly, and Quinlin wants to file a match fail. This currently hasn't happened.

  • AMY (former unofficially adopted daughter)

Amy stayed in Quinlin's apartment in Atlantis during the events in the book Nightfall. Livvy and him had taken care of her.

In Book 1: Keeper of the Lost Cities, Alden Dedrick Vacker took Sophie Elizabeth Foster to be probe by Quinlin. He was shocked to find that Sophie's mental blocking was so strong that he couldn't get to her mind. Alden said, "...She'll be the greatest Keeper we've ever known once she's older." To which Quinlin replied, "If she isn't already." The next time Sophie and Quinlin met was when Sophie was bringing Amy Rose Foster to his house in Atlantis.


  • The name "Quinlin" is Irish for "slender".
