( Wrath can see Lan Wangji's magic, sense it, feel it, and he is correct that it does feel like life- the very essence of life's energy itself inside of him, but that is not at all. The man works so closely and so often with the dead. There is a stain of that too - residual but there just the same.

He could point this out but does not. His expression remains unmoving, unoffended. Mortals have said a great deal about the devil throughout the centuries, and he has never cared what they thought, what they felt (it was only when his wife was forced to live the life of a mortal, to learn and believe all those terrible things herself did he worry, fear).

There is a pause then. )

Life and death are not as different as you make them out to be. One cannot exist without the other, and by that, I do not refer to this mirror nor to the undead shambling around, making a mockery of both life and death.

( None of this exists in Wrath's world - the dead do not linger with the living, but live in the Underworld where he rules. )

It is all about balance between the both of them.
