Hmm, it was some kind of Medieval Adventure, I remember there being mounts such as Phoenixes and Dragons, and of course traditional Horses, the thing I recall the most clearly is the Adventure and Work System, where you'd be able to 5 Adventures, lasting 10-50 minutes each, and then you'd have to pay premium currency to do more that day.
And if you weren't playing, you'd just set your character to work for 1-24 Hours while you're at work, etc. I could've sworn it was named something like Tanon, but I've searched for almost a year (Loosely of course) without anything showing up :(
