So here's a question in regards to the whole companion/summoning thing.

Emet-Selch comes from a race of people who can more or less create anything they can imagine (or if they get distracted it can create something unexpected) so long as they have the magical ability to make it manifest (which in Emet's case he absolutely does). In the faq it says that you can choose only one companion/pet, and that makes sense especially when there isn't exactly a means to swap out, say, a pokémon for a different one, or how summons are specific beings. However in his case, he would be forging these beings into existence through his own creation magic, and likewise dissipating them out of existence when he is done with them. In this regard, would he only be able to create a single creature, or would he only be able to create one creature at a time—as in, so long as that creature exists he cannot make a new one?

Sorry if this is confusing wording, I'm mainly asking this because the mechanics behind the creation magic is a little different than typical summoning magic.
