i've tried to Google it , but all i found was books related to it,,, i have a quest now at 11/20 and i cant find where to go,,, quest says " Access the holy Virtuals, the collected consciousness of the Primarchs of the past to hear their counsel " question is ; where to go ?
and btw quest 10/20 is linked to Mars, but it's on Primus planet Proterian Mons
