This update is a late update that was supposed to come in December, but i couldn't get done in time. This makes it the first update for 2015. This one comes with few new Paladin units.
There's also a short background story available here.
Unfortunately, screenshots and text don't really tell much about how units work in practice. So, here's an ingame footage of few Paladins being discovered nearby a city, and what happens after (using, at least for the time being, OmegaBolt's temperate terrain, which is available here).
That's all for this year's first news update. Have a happy new year!
