Your horse is just an evolved version of this:
It's not a real horse.
That's why you take it out of your bag (almost) anytime you want.
That's why you can't pet it.
That's why it doesn't need to go to the stables.
That's why it doesn't need to be fed.
That's why all your characters share the same "horses" even if they are half a world away.
When your character is in combat, stress makes taking the "horse" out of the bag impossible.
