But as we've already recognized, CT has at least one boundary that is significant (the NoTU to the original OTU)... I have seen quite a difference as to what the universe looks like to those who started playing without any real description of the Imperium, then those who got the earliest supplements or articles and then built their understanding there (and pasted in lots to fill the gaps), and then those who were later CT joiners where there was a lot of the OTU laid out in many products.So CT, by itself, has at least 2, and possibly 3, differing understandings of what the TU was and is.... for many are happy with where they entered and didn't like subsequent filling in...
