Andrew and Lee continue watching The Wheel of Time—and it's getting real - Ars Technica

In the scenes where Logain is facing down the king of Ghealdan, we see that the weaves he channels are mixed together with blackness—the corruption of the Dark One.

(The show also uses "corruption" over the book's choice of "taint," presumably to avoid all the memes that would come from having everyone saying "taint" all the time. Haha, taint.) Logain is beset by shadowy figures that seem to form themselves out the corruption, and they seductively whisper dark things to him, like, "Hey, you should totally kill that king guy." It's a neat effect, and I think it works great.

Whatever it is, Álvaro Morte is doing a great job of making Logain feel like the kind of bad guy who would definitely treat you to dinner plus a Bond villain monologue before murdering you.

The visual effect of the taint corruption on the One Power is probably my favorite visual effect in the series so far, strictly in terms of how economical and effective it is.

And the show uses this encampment to give us our first big dose of how Aes Sedai society is structured.

Your comment about the Aes Sedai camp showing a bit of how Aes Sedai society works is dead on, and one of the most interesting bits is watching the Green sister in charge of the camp, Kerene (Clare Perkins) keeping Red sister Liandrin (Kate Fleetwood) firmly in check.

Book readers know that among the Aes Sedai, women who are stronger with the One Power are kind of automatically in authority over those with lesser power, and Kerene (who Moiraine says has turned back entire armies with her channeling) is firmly in command.

A major job of the Red Ajah is to hunt down False Dragons and "gentle" them (that is, permanently sever them from the One Power, so that they can never again channel).

False Dragons that have great strength in the One Power tend to raise armies of followers and wreak massive destruction—as Logain has done with Ghealdan.
