Almost every town you come across will have a mount vendor. These mounts cost Mithril that is purchasable via real money. There are other mounts available in the game that are obtained as drops from bosses, but the vendor mounts will be the first that you come across and are most likely the easiest to obtain. Personally I think everyone should have at least one mount and if you buy one from the vendor then you are also supporting the game. The servers, developers, coders, advertisements, etc..all cost money and it has to come from somewhere, so why not pitch in at some point and buy yourself a nice fast mount. Iv'e checked with others in-game and so far all mounts have the same speed, but the prices, sizes, and graphics vary quite a bit. The largest mounts are the dragons and the smallest are the horses, and rhinos, cockatrices, tigers, wolves, etc.. all fall somewhere in-between.
