The city of Arshmere keeps many dangerous secrets, but Larsh Nightwave from the Octopus Clan will try to unravel them, who, due to a quarrel with his uncle, the Guardian of Arshmere, ended up in the city guard. Yes, yes, he became an ordinary “crab”, despite his high origins! A humiliating occupation for a noble young man? Everyone thinks so, except Larsh himself, for whom the world opened up with its dark, mysterious underside. A foreign nobleman died inexplicably. Is his death connected with other strange events occurring in Arshmere? Larsh will try to unravel this network - and in the meantime will receive a baptism of fire in battles with smugglers, robbers and even... a drunken bear! He called himself a guard - so don’t be timid!
