Narmythupatreon are exceptionally brutal Outsiders whose sole purpose is conquest and murder. They are violent and unpredictable warriors and are often encountered when the Old Ones launch all-out assaults in their bid at domination. They are known for their cruelty. They can move exceptionally fast, over land or water. They are excellent climbers, and efficient combatants, choosing to maul and maim their enemies to induce maximum suffering. They seem to feed from this carnage, become stronger as battle continues.
Their reputation is such that enemies facing them are often demoralized before combat is even joined.
