[Glencook-fans] Shadowmasters

We never do find out who Moonshadow is, do we? Additionally, from the Black Company Wiki: http://blackcompany.wikia.com "Returning from their journey to the North, Otto and Hagop informed Croaker and Murgen that Whisper and Blister were some of the five surviving Taken still living under the Empire's domain, albeit still stripped of their power." I...don't recall that, and I'm away from books right now. Am I misremembering, or was this actually stated?
