Viseo's Land

You make a magical invisible sphere that is 30 x 30 x 30 ft. large it can't be moved to the duration, it traps every creature to a fantasy land if they walk inside, who walked in does not know if they passed a wall or seen someone just dissapearing. 

Inside the vision creatures have 1 x 1 x 1 mile area to move, out of that they see a fake platform resembles landscapes, the horizon or the skies and can't move out from the invisible barrier. As long as they doesn't know if they are in an illusion they can't make escape checks against the spell's DC. In the area the summoner of Viseo's Land can see creatures move, talk etc. with truesight and became an invisible untouchable "God" from inside that can talk to every trapped creatures altering it's voice and cast Mass Suggestion or Dream against them once a day. The summoner can summon fake hazzards, monsters, or fake trapped persons against them as an illusion. Every round of concentration for the summoner is a day inside the vision. To break through the illusion trapped creatures can try every morning against the spell's DC, but after one morning of failed try their next morning will be a month later, the very next is one year later, after that 10 year, after that 100 year etc. If someone spends ten year inside the vision it losts the will to escape; sets free if the summoner loses the concentration or dies or stops the Illusion at will. 

On successful escape creatures drop out to an unoccupied place 5 ft. near the globle of the summoner where they kept inside knowing that it was an illusion but oldened with the time they spent inside.
