Pretty sure it only saved Annie's life, not the MC's.There is something I wonder about the consequences of something from the early game. Early on you can buy the lucky pendant for Annie which later ends up saving the lives of the MC and Annie in Eternum later on. Now this would normally lead to a loss of inventory and levels but there is a bigger problem. At the time the MC carries a gem of doom that grants him entry to a major party of all the big players in Eternum the next day and losing that gem would essentially completely derail the story. What happens if the MC didn't buy that gem?
