Enter the Demonology portal from The Hollow hub and press the Hollow button (top right).
Go into the house beside the whiteboard to be taken to the black-and-white realm.
Follow the red dot on your compass to find the altar.
Collect all six relics and place each on the altar: Altar Lantern (light the three lamps with spectral fire), Stygian Hourglass (stay inside the moving ring), Grimoire (read the three west-road signs in order), Devil Mirror (corner it on the east road), Cursed Lock (find a lockpick in crates, barrels or buckets by the park gate) and Skull of the Allseer (dig it up in the graveyard with the shovel).
Walk through the glowing door to escape.
Reward: The Way Back badge, then claim the Biter Fedora in the hub.
What was that place? We don't have that job listing on our itinerary... maybe all this ghost hunting is making us hallucinate?
- Earn this badge by finding The Way Back as part of The Hollow event
Find the entrance to the void in zone 3 (get there by fueling the campfire to level 3) then enter and collect all the flowers. Remember that you can use Lanterns as a safe-zone, and dying doesn't kill you, just teleports you out
Collect more than 75 candies from the Trick-or-Treat doors, Doors can be found in Portals with the "event" tag! Once you've collected 75 candies, return to the main lobby and interact with the Ring Alter to receive your badge.
