"Sevenstrike" was once the name of the great magic sword in Aventuria. Only the strongest among all the great heroes of the land could wield it. Later, it was melted down and shaped into seven magical chalices, which are kept in various secret locations throughout Aventuria. When united, they form "Sevenstrike," the dangerous weapon, once again. The dark powers are aware of this and are determined to seize the seven chalices. As they have already abducted six of them to the temple city of H'rabaal, the situation becomes critical. It is essential to reclaim the chalices. However, Jan Rasmussen, Kim Shayenne, and their friends cannot retrieve the heavily guarded treasure alone. They need allies to stand against demons, bloodthirsty Marus, five-headed Hydrons, and other monsters. Who will join them?.
