Since Yridia got name-checked on DSC: Lethe, it seemed a good idea for me to start digging for a location. Especially since ST Star Charts and Stellar Cartography seem to be getting regularly referenced on-screen. I've been looking via whitten.org at the sector "stack" centred on X: -50, Y: -30 and extending the Z-axis search, but so far I can't seem to find a G-class star at the right location just rimward of the X: -40 line. The closest I can find, Gliese 149 A, is a K5V star. Not quite "there", I believe, although the X-Y coordinates are close. Any thoughts? Also, since they established a nearby nebula - which doesn't exist as far as real-universe astronomy is concerned in that neighbourhood - I'm wondering if we're looking at a remnant of the Expanse from ENT?
