Magic is happening on Spheroidia and it comes from Reality-on-the-Norm. You need to investigate.
Enter Scid’s bar on the left and talk to George behind the bar. Ask him about magic and he’ll refer you to Davy Jones. Ask for an inventory item and he’ll give you a GLOBE. Leave the bar and walk to the right. Enter the house to the right of the Yahtzee brand and talk to Davy.
Ask Davy for someone to kill the magician and he’ll direct you to Baron Wolfgang’s evil twin brother. Leave the house and walk to the left, then north left of the post office. He’ll accept the job but wants you to get him a skull with a barrel of a gun sticking out his eyehole first. Walk to the right to return to the street of Reality and walk all the way to the right. Here you’ll find Harvester for everything you don’t need.
Enter the shop and talk to the clerk. He can’t help you but gives you a BOTTOMLESS GLASS in the end. Leave the shop and walk all the way to the left into the alley where the bum is located. It’s not really the bum, it’s Mike Oldfield. Talk to him and after the conversation, search the box, just to find a GOLD RING. In your inventory combine the gold ring with the glass and you’ll get a GREEN CAR. Add the car to the globe and you’ll create a SKULL WITH THE BARREL OF A GUN STICKING OUT OF HIS EYEHOLE.
Leave the alley and walk north to the left of the post office to return to Baron Wolfgang’s twin brother. Give him the skull and he’ll do the job.
