From the designer:
Her Excellency Anthelia, Blood-Countess of Kergüs, has determined to amuse herself by holding a tournament in Alliáns: the final tournament to be held before the end of all things. All the noble families of her domain have been called to attend. For months, the tourney has progressed without a victor as hundreds of nobles sought renown. Now, their banners are tattered and their armor is soiled, and Anthelia risks growing bored.
A wealthy but titleless burgher has offered to pay a late-entrance fee for you to attend in their name so that they might gain favor with Her Excellency. There is rumored to be a prize for the champion so incredible that it has stilled even the most active of tongues: to be declared the legitimate heir of the Blood-Countess...
If your tabletop group is looking for an opportunity to engage in brutal tournament combat, to hobnob with all manner of nobles, to get the chance to be bombarded with adventure hooks, and potentially to win the heart of Anthelia herself ... this scenario/setting might be for you!
