140 Explaination

If SCP-140 comes into contact with any fluid suitable for writing, including human blood, the account of the Daevite civilization’s history expands. Human blood appears the most “potent” of possible writing substances, but in any case the amount of new material does not correspond proportionately to the fluids introduced. Although these new segments sometimes include new descriptions of rituals or cultural traits or illustrations of previously covered material, they more frequently include new, more recent accounts of information chronicling the continued history of the Daevite civilization or descriptions of new individuals and artifacts. Formerly decisive defeats become setbacks; new persons and events are inserted. Foundation archaeologists have discovered corresponding new artifacts and traces of the Daevite civilization in applicable locations and strata, in some cases found in dig sites that had already been thoroughly explored.
