The Wonderful Xanthos!
Xanthos is a type of divine on Howrse that can be stroked. You can stroke five a day. The first one can give your most recent horse 10 energy points, and the 4 others determine your luck. If you're super lucky, the next day Howrse will PM you a special message. In other words, if you're lucky, you might win an HoP (horn of plenty) and 1000e!
