Ronin Challenge is an adventure module for the 2nd-edition Dungeons & Dragons ruleset set in Kara-Tur.
Until someone starts playing for keeps.
When a traitor to the empire is revealed, His Excellency calls loyal and heroic citizens to follow the trail of deception. The scale of the treachery is grand - it seems that an entire army has turned its back on its rightful liege!
The trail leads through trackless (or seemingly trackless) mountains, into peaceful (or seemingly peaceful) valleys. The emperor has promised great rewards to heroes who can solve his mystery, but as the journey progresses the heroes find their own reasons for continuing.
As a sinister suspicion grow in the minds, the adventure reaches its climax in the ruins of an ancient civilization. Finally, our heroes are faced with an ultimate choice - between success and failure, loyalty and betrayal, even good and evil.
On their choice rests the future of nations.
