"Anti-inter-dimensional portal barrier?" A man spoke with a raised eyebrow. His complexion was quite pale, littered with wrinkles that came from constant stress rather than old age. His hair was a bit disheveled and his clothes were a bit messy showing that he didn't have the time to dress up properly before making the call.
"Indeed. As the name suggests, it is a barrier that prevents travel from other dimensions into ours. Rest assured, it does not have any harmful effects on humans."
"I… would love to believe you but… does it have to be red? People are starting to panic."
"Unfortunately, we didn't have the time to adjust it to a different color. General Sanderson will provide you with the details soon so I ask for your patience."
Though he didn't seem particularly convinced, the man heaved a long sigh as his shoulders relaxed.
