1 Alvissa: <yawn>
1 Death of Insanely Overpowered Fireballs: GOOD MORNING.
2 Alvissa: Are we dead yet?
2 Death of Insanely Overpowered Fireballs: NO. HE'S STILL GOING.
3 Alvissa: Kyros stayed awake all night?
4 Death of Insanely Overpowered Fireballs: HE GOT ME TO MAKE COFFEE.

Coffee is anachronistic in any sort of realistic medieval setting, although it originates from Africa and southern Asia, so there's nothing stopping it from appearing in a pseudo-historical medieval setting without requiring wholesale changes to the history of exploration and trade.

However chocolate didn't appear until it was brought back from the Americas in the 16th century. So no double mocha lattès.
