There isn't much for Lure in the wiki beause I prefer to work from the ground up. That said, if you look at the pages for the Renkard Union, Ka'ra Mandate, and the Lank'gha Collective you'll see some historical notes. The time-appropriate border of the Lords of Thunder is also present on the Rim War era map on Traveller Map.
The UWPs remain a work in progress, and you can see that the TTW spaces in the sector are available in 1105. The dotmap is mine as well, as are all polity names.
As for the short term future, if you dig into late Rebellion TAS News items, you can find the saga of the "K'kree Merchant Fleet" (ahem) that drove into Ley and was summarily destroyed. Not identified as such at the time, it still reeks of a Lords of Thunder operation, though it *might* have been legitimate.
The issue of MegaTraveller Journal that introduces the Lords of Thunder depicts them as engaged in aggressive diplomacy across Gateway in the mid-Rebellion period.
One issue with the Gateway material in general is that it was written for two different eras (Rim War and Rebellion) but also... not. The T20 version pulls keynotes from MTJ#4 but ignores the centuries of separation. The history of Gateway has huge gaps, and some polities just sprang into existence at indeterminate times.
An additional issue with K'kree development prior to my involvement was that a few areas were done using the generic UWP process, ignoring the CT K'kree book's specific rules. Those lead to a very different picture of K'kree space, one that I'm still fighting in other fora, as Mongoose decided that K'kree are really TL12 based on nothing that I can find that makes sense. Everyone involved at Mongoose should know that the GURPS TL scale is different (GTL12 = TTL15), but that's the only mistake I can find that makes any sense at all for their assertions of K'kree TL. Much like the High Population revelations of MegaTraveller, the K'kree *worlds* and K'kree *populace* are not the same thing. Where the K'kree are "barely there" and cannot maintain their tech base, they trend lower, but the vast majority of K'kree congregate on comfortable worlds and drive the TL to its maximum of 15. Or rather, they maintain the K'kree achievement of TL15. The K'kree as a species have attained that level; it is up to each world's Steppelords to maintain it. A *very* different approach to TL than the Imperium.
