Please tell me:
* What game are you playing? Is it a specific online game, a board game, or something else?
* What is the "safe heaven" in this context? Is it a specific location in the game, or a term with a unique meaning in the game?
* Why do you need to take the horse out of the safe heaven? What are you trying to achieve?
Once I have this information, I can better understand what you're asking and give you a relevant answer!
