Violet looked from the pair of hulking WRMs - war-robot-machines - to her group of nervous students.
"A little grease isn't going to kill any of you," she said firmly. The first time was always like this. Then they'd all learn that rolling up their sleeves and getting dirty was kinda fun.
"The barrel would if it landed on you," one student pointed out.
"That's why the gravity is on," another countered.
One girl finally stepped forward to take a handful of thick purple WRM-grease and headed for an ankle.
Violet grinned.
It was a good start.
