Pendragon - I had 26ac/26dn paired by default, but then I stumbled upon a plausible answer for 26dn on its own. I'd be happy to share thoughts on 26dn if others are.
It's possible ixion, but I don't really go with the jump from "privileged information" to loo.
I thought 26dn might be loop - "party to privileged information might be in this". It's also pool (bank) rising. But I can't see how that can work with 26ac.
Yes, loop/pool is better than my suggestion. I'm not 100% sure pool and bank are good synonyms. However, we would then need a word LOOPL?C? or, depending on which word has to "rise," POOLP?C?.
