This market will resolve YES if any character who was established in the Wheel of Time book series to be a Darkfriend is 

 similarly established to be a Darkfriend in the Amazon TV series. 

Companion market for the opposite condition:

For purposes of this market, two characters are the same if they have the same name (even if a character in the show is clearly integrating parts of some other character's plot arc from the books). 

For purposes of this market, being a Darkfriend means saying explicitly "I am a Darkfriend," or similar language such as "I have sworn oaths to the Great Lord bwa ha ha." (Not counting obvious jokes or lies.) Being identified as a Darkfriend by another major evil character also counts. Also, once you start down the Dark path, forever will it dominate your destiny. Any character who has 

 been a Darkfriend counts (even if they later regret it and try to redeem themselves, or whatever). 

In the absence of a YES resolution, this market is intended to stay open until the end of the series. I will adjust the closing date as needed. If the series is cancelled before completion, I will wait for one year after the official announcement of cancellation, and resolve YES if interviews with people involved in the show clearly indicate an intent for a character to be handled differently from the books.
