Being a contract driver for a regulated transportation company with a Six-Hoofed Yak Car, he often had chances to send people to the "Scavenger" base.
He had seen enough to know very well what it meant to work as a "Scavenger".
"Scavenger" is a job that's quite respected, with good pay as well.
Many Beast Masters would take "Scavenger" as their career of choice.
Those Beast Masters who chose "Scavenger" as their occupation early on would weigh their choices in terms of beast contracts.
These Beast Masters wouldn't consider understanding the mysteries of beast-signature symbols or retaining even a hint of spiritual power, but would contract full five or six Guardian Beasts.
Then, while working as "Scavengers", they'd use these five to six Guardian Beasts to protect themselves.
Such Beast Masters, who took up "Scavenger" as their profession, usually lived very well off.
They would never even consider riding a Six-hoofed Yak Car.
