Create plain

After 2 years of spell casting a 20x10 foot portal carves itself into existence. Echos of voices streak in shrill voices as the portal morphed and worries in time and space. If the spell casters choose to enter this innate portal they enter another plain of existence. 

This plain of existence can be shaped and warped by the spell casters to there desires. They can put anything they want into this new plain but it only is 100000x200000 feet across and wide. After 2 months of living in this astral unique plain the spell casters can choose to live hear till the day they die or go back to the world and plain they live in. If they choose to stay over time there body will morph and change shape and colour.

This spell has created unholy abominations with long grotesque limbs with bulging and peeling skin long black eyes and narrow slits for nostrils. There skin peels and reels like a coil and turns a pale white as they slowly rot and decompose in pain as they turn into a living husk.

Or if they stay they turn to peak physical condition. Blemishes and scars fade as ageing is reversed and they stay young forever and live bending and creating a perfect world for them to live in and survive.
