If you liked Archive 81 and Ares then you'll love Feria Darkest Light. I wont give to much more away as the other reviews already give a lot of info. My only main complaint is that there is one episode in the middle called 'The God of Fire' which was a bit pointless IMO. It didnt really relate to the main story and didnt move it along and despite being quite dramatic it bored me because there wasnt anything mysterious about it. I stopped watching it after that one as it felt like the series was petering out and losing its direction but 6 months later I gave it a another shot and was glad I did as the story picked up the pace and direction again. My only other slight complaint is they begin to explain too much too early on, which often makes me lose interest as I like to be kept hanging until the final episode when the whole mystery is explained. That said, the mystery IS explained, so if you are one of those people who hates films or series that end without closure you will be OK with this one.
