In Black Desert Online, your mount is always present as an in game object while you are playing. You have to stake it out nearby or stable it. For the sake of immersion, we plan for the final implementation of our mount system to be a similar full time simulation: You’ll have to feed and water it, house it, protect it, and keep track of it. While we may add the ability to train it to come to a whistle or use magic to transport it, it will not under any circumstances fit in your pack.
