So from US topic a lot of people seem to think the Runecarver is Primus or else the statue in the seat of the Primus. Both valid theories imo, but then I did some digging.
I found something and wanted to add to the thread but sadly I don’t have a US account so couldn’t. So now I’m bothering my EU friends with this.
Proof that Primus is Sylvanas!
Ok bear with me here.
The Primus is the missing founder and ruler of Maldraxxus and the five houses of the Necrolord Covenant. The most tactical and long-thinking of the Eternal Ones he was a master strategist who was nearly unbeatable on the field of battle and was notorious for always thinking far ahead of everyone else. The Primus embodied the five traits of the ideal Maldraxxi soldier, traits he also instilled into the five houses: ambition, might, insight, guile, and the relentless pursuit of victory. In addition to his military might, he was also known as a legendary weaponsmith. All Necrolords receive a portion of the Primus’ power in order to carry out their duty of defending the Shadowlands from external forces.

Ok so Sylvanas is super mega tactical with her 86 dimensional chess. She beat Bolvar in a duel.
You cannot deny she is ambitious, leading the Forsaken after the Lich King fell. She is mighty hot, has great insight (referring back to her multi dimensional chess) Her guile needs no expanding upon (sly, cunning for those less familiar with English language I had to look it up myself too so don’t feel bad) and it’s common knowledge she is relentless.
Building an army of undead and weaponizing the plague multiple times for me accounts to being a legendary weaponsmith, I can only hope you guys agree.
And isn’t Maldraxxus just the perfect covenant for Forsaken?
So in conclusion; Sylvanas is Primus and founded Maldraxxus right after she jumped off the citadel.
