The previous canon of which I'm aware (MT:Referee's Companion) stated that the RoM reached TL 12. I would think that one might slip in a few experimental TL13 stuff without doing too much violence to that, but anything that was mature TL13 (let alone TL14+) seems contrary to that information.Originally posted by Andrew Boulton:
Previous canon implied the RoM was mainly TL12-13, probably with some experimental TL14. Bits of T4 stated it was TL13-14, reaching TL15 in many areas, which seems highly unlikely to many people - the Sollies were the ones with the higher tech and they were very thinly spread. They simply wouldn't have had the time, resources, or motivation to keep pushing the TL up - while dragging the Vilani along with them - as well as stopping the Imperium from imploding.
What material prior to T4 mentions TL13+ technology?
