This peice works on You. You meditate with it the first time, decide what portal you want opened and for 24 hours that portal is open in your house. Now you must be careful because this does not distinguish between WA, DA, BA, or OMG. This will open ANY portal you choose for 24 hours ONLY. If you decide you can't handle what portal you opened it does have a failsafe in it and a guardian but the guardian will NOT interfere. They are just there to make sure the portal closes in 24 hours.
