There’s a joust or a highball game at the arena today (whichever you think your players would be more interested in seeing). You’ll also want to check for encounters while they’re out on their own.
Two men peer across a long dry field and stare each other down. As one they flip their visors down, and you can hear the heavy metal clang shut all the way in the bleachers. They raise their lances, draw in tightly to the ear steeds… their horses leap forward, bright saddle blankets flutter behind in a cloud of dust, and the two warriors race towards each other.
Closer and closer they ride, closer, and lance meets steel as one is thrust bodily into the air to land with a thud on the hard ground. The victor continues his charge, and turns along the rim of the field to ride hard beneath a throng of cheering fans.
At some point in the future, your player characters should have a throng of cheering fans to match this scene.
