Carrie (2013)/ I Am Legend Crossover Prompt 2
One year after the outbreak and Chaimberlain is almost in ruins. However Carrie White manages to survive relentless attacks from the darkseekers and has hold up in one of the town's apartment complexes. She fortifies it by getting rid of all the stairs up to the topmost floor and barricading all the doors and windows via her telekinetic powers. The only way she'll get in or out of her sanctuary is by levitating herself from the roof.
Next she uses her abilities to completely demolish the surrounding buildings so that the darkseekers wouldn't be able to jump over to her location. But this feat exhausts the young girl and she takes several hours to regain her strength. Afterwards, Carrie focuses on acquiring supplies like food and medical items.
