A shaper is a psion who draws ectoplasm from the Astral Plane to create new objects or creatures here on the Prime Material plane. This type of creation results in very real beings, either animate or inanimate. When a shaper creates creatures in this way, the creatures will do her bidding. These creatures are unusual in that they are not 'summoned' creatures, but rather created ones. They cannot live forever, of course, and will vanish when their time is up. The ability to create such things makes a shaper a valuable ally in a party as well as a viable option for solitary travel.

These are optional guidelines you may follow while roleplaying your psion character. Much of it could be obvious to you from the name of the discipline. As always, you are welcome to take another path envisioned by your imagination:
Personality Traits: Shapers may have many different types of personalities. At times, a shaper may develop a 'god complex', thinking she is equal to a creator. Oftentimes, though, a shaper is somewhat altruistic in nature, creating her creatures to aid fellow people or protect a group.
Roleplay Considerations: It would not be unusual for a shaper to conjure what might look like minor 'illusions'. In reality, these are in fact creations from the Astral Plane with a very short duration. A shaper might conjure up a puff of smoke or a small toy for a child. Some shapers earn a living this way, though most with skill move on to bigger things. Some shapers keep small carvings of their favorite types of summonings to help them focus.
