Let's clarify about Abscic Binding.<br/><br/>When you summon (be it a demon or an elemental) there is a point before the test of wills when you can offer the summoned being a chance to serve you voluntarily (or even release it then and there, making the summoning a simple 'teleport demon/elemental effect).<br/><br/>A neomah might stay with you indefinatly and willingly in return for devouring a pound of your flesh, or you could crush her will and bend her personality into the shape of your slave.<br/><br/>Likewise, a gem lord's servant (Such as a Jokun) might willingly perform a task for riches to return to his gem lord. Or that Jokun could have his will crushed and molded into the form of a bound Sentinel.<br/><br/>Whatever you bind, there is something about their nature that can trigger their latent personaltiy, rather like Exalted limit, and might eventualy cause them too break out.  Or their service might elapse before then.
