Gravemind is the best poet. Literary criticism on https://halo.fandom.com/wiki/Gravemind/Quotes :

Wikipedia and halo.fandom.com claim that Gravemind speaks in "trochaic heptameter (7 pairs of heavy-then-light syllables)". Prerequisites:

• "The adjective form is trochaic. The English word trochee is itself trochaic since it is composed of the stressed syllable /ˈtroʊ/ followed by the unstressed syllable /kiː/."
• https://www.theproblemsite.com/ask/2016/02/stressed-and-unstressed-syllables
• https://en.wikipedia.org/wiki/Scansion

/ x / x / x / x / x / x / x
