Alexey Sviridov. A legend among domestic “role-players.” A born author of fantasy - mischievous, witty, exciting things. A writer who could become - and WOULD BE - a new “star” in the galaxy of the best Russian science fiction writers. But... Sviridov is no more. Only his works remain - works that no true lover of the fantasy genre simply can tear himself away from! This is INTERWORLD CUSTOMS. Customs, where elves, people, trolls and God knows what other creatures work hard. In a word, the employees of Brigade “U” are professionals whose difficult task is NOT to let smuggled magic pass from world to world. If you make a mistake even once, the consequences will be UNPREDICTABLE!..
