Let's first remember the scene where the Trollocs shout "Murdru Kar":
(A Memory of Light)
Lan’s forces stop their retreat along the banks of the Mora. The ruins of Fal Dara and Fal Moran smolder on the horizon, destroyed by their own people to deny their resources to the Trollocs. They have fourteen channelers now to set against the enemy’s Dreadlords, led by the Asha’man Deepe, and the cavalry charges the Trollocs’ ranks for the first time in four days. The Trollocs concentrate on his banner, and Lan hears them shout Murdru Kar, Murdru Kar, Murdru Kar over and over as they attack. Lan sees his bannerman Andere fall, and he and Kaisel fight to his side. Lan dismounts and engages the Myrrdraal about to kill Andere, but sees a second Fade join in, and realizes it was a trap for him.
I've read the last book at least 3 times and each time I reach this scene, I cannot stop myself thinking of what this "Murdru Kar" mean.
I don't think this is a short sentence, it should be a special name because the two words start with capitalized letters.
This may be something about Lan or Malkier but I have no other clue.
Are there any knowledge about what "Murdru Kar" means in the Trolloc language, maybe in an interview with or a blog post of the author?
