Five and its multiples are a very big reoccurring theme in Rune Master. This is both intentional and unintentional, and something that has amused RM's creators for some time. Though it has no true impact on the story itself, it is an interesting novelty nonetheless. Below is a list of examples of this Theme of Five, some of which apply to Ehrdi in general, and not just Rune Master. Please keep in mind this list is not complete, as some events that apply have yet to show online. It will be updated as these events pass, or when another five example has been discovered that was previously unknown. Enjoy!
