The Void Attunement Major Arcana does not [u]automatically[/u] unlock through the course of completing the Seasonal Questline (neither do the Solar or Arc Attunement Arcana for that matter): rather progressing the Seasonal Questline sufficiently unlocks your ability to obtain the Quest needed to get the Arcana in question. You should do the following: • First check the podium at which you can Focus Witch Engrams to see if you failed to pick up the Quest in the first place (double check to see if there is a second page to make absolutely sure). • If you do not see the Quest displayed there, check every item in your Quest tab to make sure you haven’t previously picked it up and simply forgot to finish the Quest. • If the Quest is not in your Quest tab, look through the Abandoned Quest Kiosk in the Tower next to the Postmaster on the chance you picked up the Quest and subsequently deleted it before completion.
