===Conjuration===
Each conjuration rewrite belongs to one of five subschools. Conjurations bring manifestations of objects, programs, or some form of energy to you (the summoning subschool), actually transport programs from another plane of existence to your plane (calling), heal (healing), transport programs or objects over great distances (teleportation), or create objects or effects on the spot (creation). Programs you conjure usually, but not always, obey your commands.

A program or object brought into being or transported to your location by a conjuration rewrite cannot appear inside another program or object, nor can it appear floating in an empty space. It must arrive in an open location on a surface capable of supporting it.
The program or object must appear within the rewrite’s range, but it does not have to remain within the range.

'''Calling:''' A calling rewrite transports a program from another plane to the plane you are on. The rewrite grants the program the one-time ability to return to its plane of origin, although the rewrite may limit the circumstances under which this is possible. Programs who are called actually die when they are killed; they do not disappear and reform, as do those brought by a summoning rewrite (see below). The duration of a calling rewrite is instantaneous, which means that the called program can’t be undone.

'''Creation:''' A creation rewrite manipulates matter to create an object or program in the place the rewriter designates (subject to the limits noted above). If the rewrite has a duration other than instantaneous, rewriting holds the creation together, and when the rewrite ends, the conjured program or object vanishes without a trace. If the rewrite has an instantaneous duration, the created object or program is merely assembled through rewriting. It lasts indefinitely and does not depend on rewriting for its existence.

'''Healing:''' Certain divine conjurations heal programs or even bring them back to life.

'''Summoning:''' A summoning rewrite instantly brings a program or object to a place you designate. When the rewrite ends or is undone, a summoned program is instantly sent back to where it came from, but a summoned object is not sent back unless the rewrite description specifically indicates this. A summoned program also goes away if it is killed or if its hit points drop to 0 or lower. It is not really dead. It takes 24 hours for the program to reform, during which time it can’t be summoned again.

When the rewrite that summoned a program ends and the program disappears, all the rewrites it has executed expire. A summoned program cannot use any innate summoning abilities it may have, and it refuses to execute any rewrites that would cost it XP, or to use any rewrite-like abilities that would cost XP if they were rewrites.

'''Teleportation:''' A teleportation rewrite transports one or more programs or objects a great distance. The most powerful of these rewrites can cross system boundaries. Unlike summoning rewrites, the transportation is (unless otherwise noted) one-way and not undoable.

Teleportation is instantaneous travel through the Astral Plane. Anything that blocks astral travel also blocks teleportation.
