Something that I've been asking myself since Mists of Pandaria is what are the mortal names of the Apsects? So far only one has been revealed to us, Kalec which is the mortal name of the newly appointed aspect of magic Kalecgos. but what are the mortal names of the other aspects, but your first question that I may have to answer is how do I know that they have any mortal names at all? Because of what Ysera said during a meeting between her, Alexstrasza, Nozdormu and Kalec:
While this doesn't exactly carve into stone that all three of the ancient aspects picked up nicknames it seems to strongly suggest that at least one, Ysera was planning to do so. So lets try to speculate if the Alexstrasza were to pick a mortal name which one would it be. Probably Alex crossed your mind alas there is nothing backing that.
But what do I have then that suggest that Alexstrasza has taken on any mortal name? The new 7.2.5 quest series, "the Many Deaths of Chromie":
In here we hear Chromie refer to Alexstrasza by a nickname, Allie. "So what" I hear you say, that could just be a nicknamed instigated by Chromie what is there to suggest Alexstrasza herself took it on, maybe Chromie just speaks in a very casual way to the Aspects? Actually no, at least not basing on past interactions, she in fact seems very formal when addressing the Aspects later on in Dawn of the Aspects:
With the mindset that Chromie appears formal and attempts to always keep herself postured around the Aspects it seems unlike her to just blurt out the nickname "Allie" for no reason, unless it was in truth the formal name for Alexstrasza in her mortal form. If not that is enough later on she also talks, to the green dragonflights ambassador who she refers to as Lord Itharius, keeping the tone very formal which seems to indicate that she regards rank as very important and Alexstraszas rank far outstretches that of Itharius so if there's anyone she'd be formal to it would probably be Alexstrasza.
So there you have it, do you agree with me that Alexstraszas mortal name is probably Allie or do you think I'm reading too much into this? Please share your thoughts on the matter below.
