Earth
Humanity's homeworld. Most likely the planet on which you currently reside.
In Warhammer 40,000
Since, apparently, everybody important speaks Latin in the future, Earth is known as Terra or Holy Terra. Nevertheless, it is still the homeworld of humanity and the capital of the Imperium of Man, and location of the Golden Throne and the God-Emperor of Mankind. Pretty much the best place to be. Unless you don't like gold-plated slums that still have scars from the Horus Heresy. But it is really Holy.
The location of:
- The Golden Throne
- Bears
- Astronomicon HQ
- Ptera Squirrels (which are vicious and evil creatures)
- Stonehenge ('tis a magic place, where the moon doth rise with a dragon's face)
- A palace the size of Europe
- All the Custodes
