Between my story and Jaime's, there are now a number of fictional decorations awarded by the League of Moderators. The current decorations, in their order of precedence:

Order of the Dandelion (X Marks highest honor, for tenacity and steadfastness in the face of overwhelming odds)
Wreath of Distinguished Service (for self sacrifice in service to the League)
Bronze Saltire (for commitment and courage in service to the League)
Golden Thistle (for wounds suffered from hostile forces)
X Marks Badge (for basic service to the League)
