The sun is probably the closest thing we’ll ever have to a true Eldritch Abomination. Hear me out here-
Older than recorded history; was here longer than any of us and will be here long after we leave. Has a finite beginning and end but is still incomprehensibly ancient
Burns itself into your vision instantly and can blind you if you look for too long
Further prolonged exposure can cause cancerous growths
Non-humanoid shape floating through space; colossal flaming tentacles angrily lash out on occasion
Sort of just appeared one day and is now surrounded by the corpses of its stillborn children
People used to sacrifice other people to appease it
