I found an old dotmap, possibly by L. W. L. Guatney, that included a portion of K'kree space including one sector that no-one has tackled yet - Luretiir!girr.
I've generated a dotmap sec from it (i.e. only world positions, worlds are all nameless and X100000-0), and drew borders / picked allegiances based on the Imperium Map poster. This is totally unofficial but I thought it was worth preserving the dotmap data in case anyone decides to tackle the sector in the future.
I arbitrarily decided that the large polity jammed into the Spinward side of the Two Thousand Worlds was the Dominate of the Lords of Thunder, but it will be up to whoever officially defines the sector to identify the local governments and decide which, if any, is the Dominate.
