Add a dynastic rule called “Challenges” with the following text:

A Challenge is a competition between contestants; only one challenge may be ongoing at a time, and thereafter is finished. When a challenge finishes, each Contestant has either Succeeded or Failed at that Challenge; in addition, if any contestant Succeded at the challenge, one contestant who Succeded at the challenge is its Challenge Champion.
Unless there is an ongoing Challenge, the Host may create a Challenge by publishing a story post with [Challenge] in its title, which contains the following information:

• What causes a Contestant to Succeed at the Challenge (all other Contestants Fail at it);
• Which Contestant will become the Challenge Champion if any Contestant Succeeds;
• Under what circumstances, or at what time, that Challenge finishes.

A Challenge becomes ongoing when created; the Challenge finishes when specified in the Challenge, and the Contestants who Succeeded at it, and who Failed at it, and the Challenge Champion, are determined as specified by the Challenge. Then, the Challenge Champion gains 3 Fame (the Host is responsible for updating the GNDT accordingly); in addition, the Host may change the owner of one Reward to the Challenge Champion.

Despite rule 2.3, Contestants cannot change their Location to the Reward Room unless there has been at least one Challenge, they were Contestants at the time of the most recent Challenge, and they Succeeded at that Challenge.

Add “Reward Room” to the list of rooms in rule 2.3.
