I'm around. I just tend to not post art on deviantArt much. Sorry for the delay in reply.
It was a very small team. Primarily, a classmate of mine made the site around our last few years of high school. Graconius was our main artist, but I did help make some items, hairstyles, and NPC avatars. Some others did volunteer to help while I was on hiatus to study video game development, but that information might be lost. I would have to check my backup to see if there is any traces left.
I'm currently the sole owner of Halcyon Tears, but I'm unable to revive the avatar site without staff. I'm only a writer and artist, so my knowledge of such is rather limited. I was thinking about HT recently that if I could not make a new site, I would simply create a comic to continue the story in some way.
If you want more information, feel free to send me a message with any questions.
