A number of years ago, there was a fan fiction site called Deep Angel. It started off as a seaQuest fan fiction story called seaFire ASV, but the story evolved into its own unique canon, featuring a super-cavitating submarine aircraft carrier in the near future.
Suffice it to say, it was awesome. They had a large following with forums, CGI shots, scripts, and even a game in development.
The site, DeepAngel.com, has since gone offline. Does anyone have an idea what happened to it?
