[40k] The warp is separate from our dimension, right? So if I jumped through a warp portal on a planet will I pop out on a warp version of that planet? How do planets get into the warp?

Bonus: Im a daemon how the fuck do I find a psyker to inhabit?

During powerful warp storms the veil between Realspace and the Empyrean gets thinner, so the Warp starts bleeding into reality. In extreme cases the veil can rupture and planets or even entire systems get sucked into the Sea of Souls. That is relatively rare though. There are no "mirror versions" of planets inside the Warp.


Bonus: You spend your days looking in the Warp for a soul powerful enough to shine like a beacon and then start working on eroding his mental defences until you can slip in and take control. Daemons don't really possess people though, they get either involuntarily bound into them by powerful sorcerers to make use of the daemons powers or use the psykers as entrances for a physical manifestation into realspace.
