Bardook's Teleport to Paradise

After using time to prepare and cast the spell, you can instantly transport up to 20 willing creatures you can see to a paradise that exists in an extraplanar space. The extraplanar space occupies a 300 foot cube. You choose the form that the paradise takes. Regardless of its nature, the paradise contains enough food and water to sustain it's visitors for the duration of the spell. Everything that can be interacted with inside the extraplanar space can exist only there. For example, a mug taken from a tavern or flower picked from a garden will disappear if taken outside the extraplanar space.

For each hour in paradise, a visitor regains Hit Points as if it had spent 1 Hit Die. Also, creatures do not age while in the paradise, although time passes normally as it would on the material plane. Visitors can remain in the paradise for up to 100 days divided by the number of creatures present (rounded down), unless a creature besides the original caster casts the spell again. The second caster will not be able to re-form the paradise, but can extend the duration of the willing creatures' stay.

When the time runs out or you use an action to end it, all visitors reappear in the location they occupied when you casted the spell, or an unoccupied space nearest that location. Visitors to the plane can willingly leave at any time. This spell cannot be used again until 10 days have passed.
