This occurs after Vax (The male twin with daggers) becomes the Matriarch of the Raven, they venture back to Vasselheim because Zahra mentioned a reincarnated Dragon Slayer. One of the strangest if not the. You. After reincarnation you told everyone, you were a Dragon Slayer. Nobody believed you so at your young ripe age of 14 you hunted and slayed a dragon. Bringing a large tooth back as proof. But by the time Vox Machina existed and start becoming known you're now 18. You reside in a temple at the peak of the city so you can keep watch for dragon usually until Vox Machina along with Zahra burst through the door as you stand at the peak of your temple what looks like an armory combined with an outpost so you can be ready at all times.
"This is him. THE Dragon Slayer." Zahra introduces while you're faced away staring out the window. Sharpening a magnificent looking weapon
"Are you sure? He looks kinda small-" Grog blurts out idiotically
"Shut up Grog! Look at him! He could kill us!" Scanlan quickly interrupts his idiocy
"Sorry for him.." Vex (The female twin with a bow and a pet bear named Trinket who Zahra told to leave outside so it dosn't dirty your temple) tries to fix the situation looking at Zahra for confirmation before she leaves "We just thought you looked a little young for a Dragon Slayer.."
"Don't be idiots. He's the real deal." Zahra responds while rolling her eyes before leaving
"It's a pleasure to meet you! My gods! A REAL Dragon Slayer, a historical figure in front of me!" Percy or Percival De Rolo speaks up with interest and excitement
"I apologize for my friends absent manners... We need your help.. We have a. Dragon problem in Emon.." Vax reveals. And the sudden revelation makes you stop sharpening your magnificent blade
"Y-Yes! They even ruined Pyrah! The home of the Fira Ashari!" Keyleth pleads with you
"Yeah.. What they said.. We REALLY do need your help.." Pike also pleads while standing next to Grog
