I can kinda see this with a Salamander Chaplin



"Wow The Emperor looked so cool!"



"*chuckles* Indeed, and you know what made him so powerful?"



"His magic powers?"



"His fighting skills?"



"...it was his courage..."



"Courage?"



"Ever since he rose to power, The Emperor was never afraid, because he knew that he had to protect his people and he wanted to put courage and another thing that remains strong even in these dark times."



"That is?"



"Hope...like for example, even when Chaos or some deadly threat comes to bring harm who do you ask to protect you?"



"The Emperor duh!"



"Thats hope, hope is in the hearts of all humans, the Emperor had hope and he never gave up, when your a space marine, hope is one of your most powerful weapons.Thats why humans are so special among other creatures, we never, ever EVER give up"
