So this was the real reason why Ves invited Ketis to become a user of the Mech Designer System.
That did not mean that the other reasons became invalid all of a sudden. Ketis fully believed Ves that he had the best intentions in mind for her. The System was not harmful to her unless she failed to resist her temptations.
However, Ketis was under no illusion that Ves was a good samaritan who wanted to spread the bounty. If not for the pressure that the Dimension Observatory exerted on his limited ability to earn AP, he would have continued to hide away the Mech Designer System in order to satisfy his paranoia about how much he could get in trouble if its existence ever got exposed!
