GLaDOS

You woke up after a long, long slumber. You’re in a small room, with a timer above a white strip. After the timer inevitably ends, a voice begins to ring out through the laboratory.

“Hello, and again, welcome to the Aperture Science Enrichment Center. We hope your stasis was comfortable, because you have been asleep for a very long time. Regardless, you are now awake and ready to better humanity.”

A blue portal then appears below the timer, with an orange one outside of the small room, you can see through it.

“Please step through the door to begin scheduled testing. There will be cake served after the test is over.”
