It is said that the key to gain entrance to the Black Lodge is fear —usually an act of brutal murder. This is in contrast to the key to the White Lodge, which is love. Another requirement to enter the Black Lodge through the entrance in Glastonbury Grove is that it may only be entered "...when Jupiter and Saturn meet..." When the above requirements are met and one approaches the pool in Glastonbury Grove, red curtains appear, which the person walks between before the curtains vanish once again.
