From the introduction: If the Biosphere in the Fountain jump seems a little… threadbare, you can upgrade it to a full remodel by spending 400 CP instead of the 100 CP listed in the jump document (Discounts still apply… and if you apply both of your Item Discounts and use your freebie you can actually get it free. 400/2/2=100, you’re welcome). The Biosphere Remodel gives your Warehouse an exterior. Outside your Warehouse is now a bubble universe, a celestial crystal sphere that looks out on the vastness of the empty infinite. Don’t worry, you can make it opaque. The Warehouse rests on a small floating island that is yours to customize as you like. Note, this does not expand the size of your warehouse, though if you have Housing and buy Freestanding, it will move your Housing outside of the Warehouse, so that will free up a little space.
