d30 feature will appear in the "NPC" section of the d30 Sandbox Companion, and will appear alongside the likes of the NPC Traits Generator, the Sage Generator, and the Quick Magic Item Generator.
The main section of the chart is loosely based on the Myers Briggs personality types. And though some of you might look at that section and say, "Hey! That's not a d30 chart! That's a bunch of d10 charts!", the idea is that over time DMs start to know which 3 sub-areas to use (to create a "custom" d30 chart) to round out they game they want to play.
Some of you may also recognize the column on the left from the d30 DM Companion. The d30 Sandbox Companion takes the NPC items that were included in a measly 2-page spread in the d30 DM Companion (like the ability score "slot" tables), and really "blows them out" to the extent needed by a DM running a sandbox game (16 pages total if you include things like the language determination page, as well as the hireling/henchmen recruitment pages which have yet to be completed.)
