While I don't think this should be open all the time, this is really nice to play with once in awhile.
In the ~24 hours since it's been online, I tested several builds, hunted in a new area, wrote a complete wiki article (okay...technically I forked an old one and fleshed it out), and was actually crying laughing at various points last night.
Every once in awhile, it's fun to summon like a dozen abyran'ra in a single evening without being a GM.
