All you Need To Know about the 6th season Premiere of Game of Thrones, "The Red Woman,"

The sixth season premiere of Game of Thrones, titled "The Red Woman," ended with a major shocker for viewers, as the titular character — the Lady Melisandre — revealed that she's been keeping a very big secret since she first appeared on the series.

As unveiled in the episode's final scene, Melisandre has been keeping her appearance magically disguised all along. Her true visage isn't that of 39-year-old actress Carice van Houten instead, she is immensely older.

It's a revelation that certainly makes us look at some earlier scenes  like Melisandre's seduction of Stannis Baratheon back in season two and attempted seduction of Jon Snow in season five in a new light.

And it's another example of magic taking a more prominent role in Game of Thrones as the series moves toward its conclusion.

The big question, of course, is whether Melisandre's magic is powerful enough to raise the late Jon Snow from the grave. And while we didn't get an answer to that this week, Jon's body remains intact and in prime condition for some magical reanimation.

Overall, though, this twist won't be a surprise to the most avid fans of the series — it was set up well by George R.R. Martin's books, and van Houten actually said her character was over 100 years old in an interview back in 2012.
How can Melisandre change her appearance?

Well, she's a witch with magic powers! But, more specifically, in the books we get more details on this type of magic, which is called a "glamor."

In the most recent book, A Dance with Dragons, Melisandre tells Jon Snow that the Lord of Light has given her the power to create illusions:

"Call it what you will. Glamor, seeming, illusion. R'hllor is Lord of Light, Jon Snow, and it is given to his servants to weave with it, as others weave with thread."

Later on in the book, Arya Stark gets a brief explanation about glamor magic too, from her mentor in the Faceless Men:

"Mummers change their faces with artifice," the kindly man was saying, "and sorcerers use glamors, weaving light and shadow and desire to make illusions that trick the eye."

Melisandre puts those powers to use in that book. She reveals to Jon that she had faked the dramatic execution by burning of wildling king Mance Rayder by substituting another wildling in his place and "glamoring" his appearance to look like Mance.

Furthermore, she reveals that certain objects with a strong connection to a person can be used to strengthen the illusion. In Mance's case, he's wearing the Lord of Bones's "bone armor" to look more like him.

"The bones help," said Melisandre. "The bones remember. The strongest glamors are built of such things. A dead man's boots, a hank of hair, a bag of fingerbones. With whispered words and prayer, a man's shadow can be drawn forth from such and draped about another like a cloak. The wearer's essence does not change, only his seeming."

In Melisandre's case, the magical object helping her weave her illusion is that ruby necklace she usually wears.

We also learn that glamor magic isn't easy for her it takes serious effort. "They need never know how difficult it had been, or how much it had cost her," she thinks.
