Quick answer: The astrologer's location in Graveyard Keeper 2 is the Astrologer's Tower at the Port: go east into the Port district and enter the odd-looking building beside the giant foot, on the middle right of the Port. He is Gunter ("the Mysterious Guntarius"). The Port is locked until you win your first big town battle, so if you can't find him in town, that's why. He's there all week; only his quests depend on the day.

Players search astrologer location and where astrologer; if the Port isn't open yet, he can't be reached. German and French players search Graveyard Keeper 2 Astrologie; it's the same place. Some players on Steam ask where is Herbert the astrologer?, but they're two different people: Herbert runs the guards, and the astrologer is Gunter.
