Pandora

Pandora is the mysterious planet. It is a barren, desolate world filled with dangerous creatures. Pandora's habitable regions appear to derive sunlight indirectly from the reflection of its moon Elpis. Pandora has a 90-hour day and takes ten Earth years to orbit its sun (one winter is seven earth years and a summer is three earth years). Pandora was first settled by humans during a winter season, when much of its wildlife was hibernating. After seven earth years, the warming climate in that region has resulted in most of the known native wildlife (excluding rakk hives and some other unknown or undiscovered species) waking from their hibernation, all of which are hostile to Pandora's new human settlers.
