IS-EDZ can be identified (if by some circumstance you were not aware of your arrival into the space) by an almost infinite volume but not quite, various methods have put the volume at between 4.973x10^1934921 and 5.129x10^2031924 kilolight years, which by any system is edging on infinite in real space although the reason that it is called near infinite is that all measuring equipment seem to be showing forced results with no deviation in that specific tool despite a breadth of tests which should in any case reveal different results. Another feature of IS-EDZ are the occasional skeletons of creatures of sizes impossible to sustain internally, even given the generous estimation of being near perfect beings, some of these creatures in fact outsize ON itself. Although none of the living versions of these creatures can be positively identified, some readings have shown that there are creatures living within IS-EDZ, unfortunately it is not possible with current tools to reach them for further study as the trips there would take over a kiloage.
