Wait, that part is kind of new. And if it appeals to you, you should probably take a look at World of Midgard's new Kickstarter project. The game is currently running in a beta state, but the development team wants to move forward and complete the game in a suitable fashion. That means a need for money, and that's why the game is opening the doors to crowdsourcing.
The project offers an exclusive mount for players who donate just up to the $15 level, with increasingly extravagant rewards for those who offer more. If it sounds like your cup of tea, take a look at the project and consider sending a few dollars along to help development.
