As of now, there is a free horse rezzer next to the FC Welcome Center. Just touch the horse and choose the type of horse you want. If you can’t decide, touch the sign and you will get a picture of all the choices, listed from tiny ponies to huge Clydesdales.
When you choose a horse, it will rez and you will be sitting on it. Turn your AO off. You get a HUD that let’s you control your activity, speed, and many other things, or you can just use the arrow keys on your keyboard to keep it simple.
Ride the paths of Faery Crossing. To get from island to island, use the fords, or just wade into deep water (and watch the fun animation). Form a faery rade by choosing to “follow” another horse rider – you can sit back and enjoy the view!
If you ‘stand’, your horse will wait patiently for a short time in case you want to get back on or have it follow you or lead it. If you don’t follow up with a new activity, it will eventually disappear.
You can always go back and get another horse!
