Mayalaran is the name with which Adolin's dead spren Shardblade identifies herself to him by tickling his mind, very faint, like a sigh. Upon learning this, he affectionately calls her Maya and invites her to bring down a thunderclast with him.
She is a blue one-edged blade. Her sharp side is sinuous, rippling like an eel curving up into a point. Her opposite side has delicate ridges, with the appearance of crystal formations. She is six feet long once summoned.
It is presumable that Maya might be able to be resurrected.
