Create hydrogen in the void. Create lots and lots and lots of it.
[4] Hydrogen spreads out through the void, clumping in some places.
Grow larger, MUCH LARGER. MUHAAHAHAHA
You don't have an actual physical form, so...sure.
Fuse the other universal edges together to turn the torus into a Klein Bottle.
[1] You trap yourself in a Klein-bottle alternate dimension. Then a garbage can and a nonut hit you in the metaphysical head.
Make oxygen.
[4] Oxygen created.
Make habital planet.
[3] You create a planet which would probably be habitable, if it was near a source of heat and light. I'll call it...Toh.
Create intelegent life on planets.
Also make more solar systems.
[5] You create a whole ecosystem of aliens--two, in fact. The Dertakans are trolls made of fire who have large litters. The Furmeans are thin, with slug-like bodies and specialized limbs. Other notable species on both worlds (which share species other than their races) include a race of spindly creatures who reproduce asexually and are symbiotic with plants; one-eyed bears which reproduce quickly and have four tentacles coming out of their backs; cantankerous cattle made of earth and stone; a small dolphin-like creature with a complicated life cycle; and a race of clumsy fish with stinger-tails and stubby arms for pectoral fins, probably explaining the clumsiness. Phew. I'll...I'll let other people name these species.
Make another attempt at this Pocket Dimension thing
You notice a Klein dimension. [5] Now it can only be entered! You toss the nonut and garbage can in celebratoraly!
