As you walked out of the house of lamentation, you saw a fast, red car stop right in front of you, with the driver as... mammon.. mammon was the driver.

-- "YOOO HUMAN! GET ON, WILL YA'?!"

he asked, laughing loudly as he pressed the car honk, waiting for you to get in.

-- "CMON! DON'TCHA LEAVE THA' GREAT MAMMON WAITIN'!"

where did he even get such a nice car..? well, it's mammon, no explanation needed just for that.
