"You can sign the contract if you want to participate, but know that you might die." The head butler's assertive voice reverberated across the field. 

Some couldn't believe their ears.

"Die?"

"We're here to apply for a job. Not to die!"

"This is crazy!"

"We just applied to be a Servant!"

The murmurs turned into roars and finally devolved into yells.

Varian stayed silent at the irony. 

Didn't these people see those hover cars turning into ash? 

A few people just died because they tried to trespass after the time limit was reached.

Do you expect a 'safe' test from such a clan?

"Take it or leave it." The old man was imposing. From boo's info, the old man was a Level 8 Gravity Awakener.

But he was very old and was nearing his death. The succession for the next head butler was already going on in full swing.
