The Great Cataclysm
657 years ago by Arkhams calender the great cataclysm occurred. Reducing whole countries to ash and ripping scars across the surface of the world. Most believe that the cataclysm was caused by an alchemical war and that the reason for Arkhams strict Isolation policy is to prevent such a war from happening again. Regardless of the reason most of the recorded histories were lost to the almost total destruction and though scholers did what they could to preserve the knowledge huge swaths were cut both into the annals of history and progress of the alchemical craft. Some believe that some of the worlds history may have been preserved in countries outside arkham and that ending the isolation policy could benefit all of the city. Others question why the so called immortal alchemist who has lived through the cataclysm doesn’t simply share her knowledge and the fact that she doesn’t leaves her in a rather unpopular position among the common people. Despite this she has refused to even comment on the matter or the accusations.
Some things besides the immortal alchemist are known to have survived the cataclysm. The Dark Tower and The Garvegian Line have both stood since long before the cataclysm for instance. Regardless of cause the great Cataclysm was a calamity that swept the whole world and any who lived through it were said to have been scared to the core barly able to maintain enough motivation to rebuild at all. Trying to forget as quickly as possible and for the most part that is what most of Arkham has done.
