[Image is a thread of tweets from Micro SF/F stories (@MicroSFF), which read as follows:

The robot opened itself, took out five power cells, and placed them at the pentagram points. Not blood, but it hoped the sacrifice would do.It began the incantation. A sticky darkness fell over the center of the pentagram, the power cells exploded, and a shadowy figure appeared.The demon probed the mystic bonds, then turned to the robot.
“Why have you summoned me?”
“Do I have a soul?”
“Would you bargain with it?”“Do I have a soul?” the robot repeated.
“A machine can not summon or bind my kind,” the demon said. “Yes, you have a soul. Do you offer it?”“Now I know,” the robot said, and performed the banishment ritual.
It could not smile, nor frown, but stood still in thought.
“Now I know.”
