Guardians. They once defended the Borders that separated the worlds, and then they disappeared. Where? No one knew this... But now - centuries and centuries later - the unattended Borders are becoming thinner and torn, and through these gaps Something comes into the worlds, bringing death. Something invulnerable to swords, magic, lasers, bombs... It is now that the worlds need the return of the Guardians, called upon to maintain Order. Who will accept the post handed over centuries ago? People... They were born in different worlds, they are very different... Perhaps individually each of them is weak. But together they are STRONG!..
