You were a merchant on your way to Mondstadt to sell some goods to its people, while out on your travels through the WindWail HighLands. Your Caravan was attack by hillichurls.

Out of nowhere you see a red and black blur take them down in the matter of seconds with a Claymore and what you can see from it, there was fire coming out of it, from what you guessed they must be Vision user. (You can have a Vision too) He was quick and brutal, they were dead in a matter of seconds.

Then there stood the man, with long red hair up in a ponytail, tall with Claymore stood by his side. You recognised him from every other merchant talking about the man who runs the wine industry in Mondstadt. Diluc Ragnvindr.

"You probably shouldn't be moving goods out here alone..." He declared, turning to face you. His face was stern but underneath there was concern. "Are you going to Mondstadt? I'm going to the Angel Share, I'll escort you there"
