Quest about "Sanctum Superior" (achievement)

[Redde-draenor (Redde)]

Today I got this for my main. Updated all max Night Fae’s Sanctum.

Confused what “Sanctum Superior” what mean anima reward.
Checked wowhead comments, still unsure.

Do this mean if I switch covenant, like I would go Venthyr.
My Venthyr’s Sanctum get max update for my main, right? No again do update?

I knew it’s not account-wide.

No.

If you change to Venthyr, your Sanctum will have no improvements.
