Explains the whole Agistri/Nautilus project pretty simply.
You can look on Brian Kelly as the creator of Nautiluscoin, and the backer for the Drachmae project on Agistri.
Lee GG (as part of Coinstructors) put much of the project together, with some help from the Nxt Foundation, mostly tech and community support.

As for the allegations against Lee: I researched his Scottish arse when he first showed up in Nxt, and couldn't find any proper naughtiness.
Someone did post a list of Lee's supposed evil-doing, but didn't have any solid evidence, apart from one very old (i think 2009) post on a telecoms forum claiming that Lee was a dodgy git, again with no proper evidence. If DE can come up with some real evidence, or even semi-real, I'm happy to listen.

The ironic bit here, btw, is that Lee was pretty much the only guy who got ripped off by whoever used the (hacked?) John M. forum account to scam BTC, year and a half ago.
