After resting for a while, Jareth decided to hold a press conference to tell his findings.
There were hundreds of mages gathering and trying to contact him constantly, and talking with each of them one by one would have been a great pain in the A*s.
Although Jareth can sell the information about the Abyss Altar Area for quite some money, he isn't poor; he has so much money that he can't spend it in his whole life.
Moreover, this world's going to be destroyed anyway, so having more money is pointless as it will lose its value once he leaves this planet.
Using this information to gather the items he wants to find would be much more effective.
Jareth held the press conference and put up a list of rare items on display.
He provided everyone with basic details about his journey through the endless horrors of the Abyss Altar, but he did not divulge too much detail.
