Imma be honest, this one just never clicked for me. I'm cool with all the things in SCP that are just spooky or creepy but I never found this one that interesting.
@jasty if you we're reading, it appears randomly on battlefields. Just like that old man who gives the lonely dying some comfort before they go, this one is uncontainable because of their nature.
Well, to be fair, this one is an actual mythological creature that the creator decided to turn into an SCP.
Most of the time, SCPs just happen to be vague or unique entities that were given identities or backgrounds by their creators.
In this case, it was an already existing mythology, just given a slightly different background, hence why it appears to be less interesting in my opinion.
