Hi there! I'm actually working on a more low-powered SCP/Backrooms Jumpchain story that will feature Essences, eventually. I'm hoping to finish and publish the first chapter today, but should get it done by the end of tomorrow at the latest.

i will be waiting and i am very exited ! no one write these jump stories involving meta essences exept that one with gatcha in marvel one it has only one essence and i tell u the guy did a very good job in exploring that particular essence and the mcs personality is badass too! 

 with a ruthless lonewolf mc like cosus u could start a story like said in the original starting ur character infront of the mysterious cloked dude who presents u any type of essences but with a limitation to only 7 this could be tried with different mcs with different essences and jumps so much potential so many ideas like going and messing the orignal plot of famous anime manga like death march man talk about hatable mcs! alas i am no writer ur!
