I hope the pack has mermaids

More like it better have mermaids, since we have been denied Occults forever. I don't even need them to have the same feature depth as vampires, though there is no reason for them not to as we are talking about an EP and they are supposedly the only occults that fit the pack theme.
Still, in the end I'd much rather have some of my favorite Occults even if not as meaty as Vampires than not having them at all in TS4.
