I’m not going to provide any spoilers or specific answers. Genuinely I'm not confirming there’s any connection. For sure there are parallels between the Titan Pantheon that rules over our plane of existence that we’ve seen in Azeroth and sort of the ‘Pantheon of Death’ that has ruled over the Shadowlands. There are parallels there that are going to be fun to explore.
Thrall: Hold. I hear something...
Helya: Your unworthy souls will feed the coming darkness!
Lady Jaina Proudmoore: "Unworthy"? I hear you were beaten quite soundly by "unworthy" champions, witch!
Helya: You will pay for that insult! The skies of your world will be darkened by the wings of my Mawsworn!
Thrall: For Azeroth!
Helya: Drown! Drown among the souls of the damned!
