 The Treaty forces both sides to keep the balance on both sides and grants either side the right to an equal act of light or dark if either side uses their power on a human or other, and limits their actions.Light Others created the Night Watch, to make sure that the Dark Ones keep the Treaty while the Dark Others created the Day Watch, to watch the Light Ones.The Inquisition oversees both sides and prevents either side from gaining dominance, because, as noted in the twilight watch, dominance for either side means defeat for Others, serving to punish either side if they violate the treaty.
