Yegor is a veteran of the war with demons, the owner of a diamond time card. Hero, soldier... and almost dead. An attempt to escape death throws Yegor deep into the past - a year before the demon invasion, the day he received the card. Great! In a year, you can prepare for the coming apocalypse, especially with an incredibly powerful map, familiar to the last diamond glare. But instead of the usual time map, Yegor gets another.
