Select an area within range. The area is a cube that can be as small as 5 feet and as large as 100 feet on each side. You use the memento from the feywild to make a tear between the plane you are in and the Feywild, manipulating it's energy. If you try to cast this spell in the Feywild, the spell fails (the spell slot is lost but the components aren't). As such, the area gains the following effects: 
Time in the area passes in a fashion of your choosing. Choose one between:  

• Days in the area become minutes outside the area. 
• Days in the area become hours outside the area.
• Days in the area become weeks outside the area.
• Days in the area become months outside the area. 
• Days in the area become years outside the area. 

Whatever you choose, the setting remains the same for the whole duration and the time measuring device will always show the time outside the area. You can also choose how your body ages, following the time inside or outside the area. You can also apply any or all of the protections as per the Private Sanctum spell. The spell lasts until dispelled, and you can dispel it as a free action. When it is dispelled, the device disperses into dust and is permanently destroyed.

For every year you spend in the area, make a DC 10 wisdom saving throw. If you fail, mark down one failure. Every time you try to leave the area without dispelling it first, make a DC 20 wisdom saving throw. If you fail, mark down two failures. If you have 5 failures in total per unique casting of the spell, then your mind gets absorbed by the potential of this magic and you lose any and all willingness and ability to leave the area or dispel it.
