((The sun has turned on us. What did we do to deserve this fate? No one will ever know. Day has broken, and now anything that touches sunlight will suffer a fate far worse than death.))
Day 1, approximately 3 hours after day broke. You woke up to screaming outside your home, as sunlight transform every living organism it touches into piles of amalgamation. After what seems like ages, the screaming stops. Everything is now dead silent, and the only sound you can hear is that of the emergency announcement on TV. — The SCP Foundation has interrupted your standard broadcast for an extinction-level Apollyon announcement. Due to a certain [REDACTED] event, all citizens are advised to stay indoors and block out all natural light. An approximate [REDACTED] billion casualties have taken pace within the first 30 minutes of activation. Stay away from all visible light (390nm to 700nm) emitted by the sun. Stay away from all visible light (390nm to 700nm) reflected by the moon. Refuse all requests from people attempting to enter your home, no matter how human they may seem. This message shall repeat until there is no one left to hear it. Embrace the darkness. Fear the light. Secure. Contain. Protect.
