SCP-990

SCP-990 is a Keter-classified SCP.

Description
SCP-990 is a friendly business-suit-donned man who exclusively appears in the dreams of SCP Foundation personnel and tells them about upcoming and unfortunate events, one of these events even being the end of the world; a nuclear war, that SCP-990's warnings averted.

While SCP-990 insists his warnings are prophecies (or wake-up calls as he labels them), his Keter-classification originates from the possibility that they're threats he's causing. As evidenced by an "interview" (recalled dream) with a doctor, SCP-990's warnings are all leading up to stop an unborn SCP very far into the future, as he labels this SCP the "bad guy".
