Created for YunieRozier's To the Humble Monthly and Beyond! event.

"Portals.... Found buried on Earth. Who made them? We know not. Now we humble humans use them to travel to the stars."

We have a new mission for you: planet Gliese 581. Tests indicate relative safety. Space suit will be required. Gravity 0.15g. You will find oxygen bubbles in the atmosphere.

Beware of the fauna, stay alive and find a portal to come back for fame and glory!
