Anyone read the article on wowhead or seen the Taliesin YT video about it? Its a long one, but in essence its speculated that the primus is the real jailor and zovaal was nothing but a puppet. Also, the wording of Maldraxxus(and some other words related to that covenant, cant recall) is coming from latin and they mean "evil dragon".
Its a long speculation thread, but honestly, i'd like to believe all of it. It also fits the way Blizzard tells a story, never really revealing anything but dropping small hints everywhere that can be really hard to see.
In the end the article says:
With both those things in mind, I will point out one possible interpretation for the name "Maldraxxus".
"Malum" - Latin for evil.
"Draco" - Latin for dragon.
Maldraxxus, loosely translated, means "evil dragon".
