Wherever 12L sits in your chart, it can show something that haunts your mind, the Obsession you may have, and which can lead to harmful effects in your life
For example, if 12L is in your 9H under Malefic aspects, it can point at you being so focused on the harm you suffered in childhood at the hands of your Father or a Teacher (or during a long distance journey), that you cannot let it go and it shapes your destiny in an unfavourable way if not controlled
