This is great progress, Nuughe might cause a change to Nooq - are the Inheritors and their Sphereworld canon, or do we wipe them from the map?
Somewhere in Bar'kakr is Ktuuxtlligh (?) - Subsector K? (CT Aliens 2. has it on the map)
Also from the GURPS Aliens 2, there should be a world at Gnaa Xarr'rr (Gzirr!k 1916), where the K'kree/Hiver Treaty was signed - This is missing from the Gzirr!k on Travellermap, which I generated, so feel free to add it. I can't see any further information about it.
GURPS Aliens 2 also mentions "New Beginning", a Human world in annexed by K'kree Kaa G!'kul Sector (no further details)
