This is an Oddquain, the name is as odd as any I have come across. An oddquain is a 5 line poem, unrhyming lines, but with a meter of 1-3-5-7-1. There are several style of oddquains that use additional lines and or different patterns. Below is what is called a Butterfly Oddquain that uses the meter pattern of 1-3-5-7-1-7-5-3-1, it is also called a Mirrored Oddquain. Something about rules and respect that sometimes people forget (and no spoilers).
