Into the future

This campaign is a long term campaign about 4 people from before the time of dinosaurs back in a fantasy world where magic and dragons were not just fairytale where adventures would seem ultimate glory however the 4 chosen were nothings relevant to history but not for long one day they are going about their business when all of a sudden a Crack forms in the sky and they are transported into the future one with no magic no dragons where they get hired by a government agency,  Agency for Temporal Law Anomaly and Security or A.T.L.A.S for short where they are told about anachronisms being caused due to the Cult Syndicate for Temporal Occupation and Reality Mastery or S.T.OR.M for short they are trying to take over the world by bringing creatures and people from the past to the present it is up to these 4 heroes to stop them by any means necessary  I am looking for both a DM and players  I also have an artist for artwork Discord justin_p2009
