Gladiator
Harry was not expecting Ron to be in such a chipper mood after Herminie spent half the night yelling at him to get his shit together or ells she would break up with him. Ron was in such a good mood that Harry just had to ask, "Ron, why are you in such a good mood?"
Ron gave him his best shit-eater grin and said, "Haven't you heard, everyone fourth year and older has been invited to the ring next Hogsmead weekend."
Herminie, who had been sitting a seat down finally gathered the courage to speak in front of Ron, "What Ring?"
Ron sputtered and said, "The Gladiator Ring of course, it's the final championship!"
Herminie and Harry both went pale and Harry asked, "Don't Gladiators fight to the death?"
Ron frowned and said, "Oh well, figuratively, but no one ever actually dies in the ring, theirs spells to prevent that."
Herminie frowned and asked, "Wait so how does someone becomes a Gladiator? The Roman's used slaves."
Ron frowned and said, "Well I'm not sure all the details, but all the Gladiators are normally a percentage magical creature, although there is one girl who's just got a wicked Animigius form. To get to the tournament you have to have won at least twenty bouts, you have to have won at least five tournaments over the last decade to get into the championship. It's been so long since a Championship was held in our area, and it's going to be held in Hogsmead! I've only ever been to one bout before, but it was even better than the World Cup!"
Harry frowned and asked, "Why would anyone want to fight to their metaphorical death?"
Ron frowned as he puzzled over that for a second then said, "I don't know, but it's wicked. No wands allowed, and sometime there are even dark creatures. The bout I saw was between giant and a rogue Veela, The Veela wiped the floor with the giant! It was so awesome!"
Ron continued to talk about the Ring the rest of the day, and before long had both Harry and Hermione promising that they would come.
