It's very rare that this stallion will show himself.

he usually only answers the cries of the lost.
but its never a good idea to get lost in his woods.
you never know what he will demand or take for helping you out of his domain.
but then again, he may ask for nothing, possibly knowing you'll be returning to the woods once again.
maybe just maybe. he'll let you loose yourself in his woods and you'll never escape his grasp.
