The boundaries of your pocket dimension expanded, stretching 100 meters in length and 49 meters in width, the size of a football stadium.
Over time, this space will continue to expand autonomously. With each passing month, your dimension will burgeon, expanding outward from all sides by an additional 100 meters. Up to a maximum to the scale of Earth itself.
You can summon and resummon anyone of your choosing, but that's the extent of your control. This space has the conditions to sustain life the same as earth.
