I Eat Danger for Lunch
Snakes aren’t usually a sign of good fortune. If you encounter a snake, the best thing to do would be to run away from it and never look back. In the Harry Potter books, we know that snakes are magical creatures that eat humans and become Horcruxes. However, some snakes aren’t mean at all.
The Rod of Asclepius has become the international symbol for healing and medicine. The single snake wrapped around the road wards off evil diseases and infections, which definitely fits this person’s scar extremely well. Whether this is a work in progress or the staff serves as an invisible rod, no one can say for certain.
