The official guide mentions this on page 135. Like the e-shaped rooms in level two of No Remorse and level six of No Regret, this is the work of Eric Willmar. I haven't seen it documented anywhere on the Internet, so I made a short video. Enjoy:

Hey everyone. It's great to see that some people still enjoy this wonderful series.
In the hopes of contributing to the Crusader community, I've started a No Regret playthrough. As of today, the videos for level one have been uploaded to my YouTube channel. I'll make more videos as time...
