Backstory

Gobby tells you that the egg is nice and warm and stirring. She’s excited. Lilanca has made you a bed by the window and you sleep comfortably for once, but before you are completely awake, one of the house boys shakes you. He fears you slashing out with some hidden weapon like most guests. That must explain the heavily padded armor and shield he is wearing for task. As soon as you wake, he runs.

I’ll approve those modest purchases. Is the name change not just for the bath scene? If it is a character change I’ll make more of it before proceeding with the story.

I think the AC rules make a little more sense that you give them credit. The chain mail is worn with padded gherkin and other things. The whole ensemble is calculated better then leather itself. In the end, it’s a mechanic that makes the math easy and the role playing more fun. If you want to get your head stuck in the minutiae then I recommend you play in 3.5e. You would love it.

Yes, the name change is for the overall game. I'll let you know as the game flows when I'll use aliases for specific uses.

It is still easy enough to find the central square in the dark before dawn, even if it by hearing the play of water where an aqueduct drops ice melt mountain water into various cascading basins.

As you reach the end of the street that empties into the square, you hear the sounds of hoops and howlers, as well as the clank of metal, and the sound of a very young girl crying in fear. Getting to the edge of the dim lit square, torches on the perimeter and the growing dawn approaching, your eyes confirm what you have heard. Five soldiers in plate mail and drawn long swords are pushing around a girl of perhaps 10 years old, who is carrying on her head a large pottery that she has filled at the fountain, the water spilling as she moves back and forth to avoid the men's swords set out to trip her in jest. You hear one of the men yell out in broken Maztica common, "Dance for us squaw!" You can see no one else is in the square and all the shop doors are closed. They are 80 feet from you and are at the center of the square.

At second level you get Action Surge at third level you select your martial archetype, which allows you to do two actions in a round, once a long rest.

Picking an archetype allows you to role play more things than just singing an ax. There are some fun ones in this link

I have been reading through the PHB about fighters and spells. I picked my two cantrips, but not my three spells. I'll get my character sheet updated ASAP.

I highly recommend "Shield" especially at your level. More useful than an attack.

It is a reaction so doesn't impose any action economy problems.

There is a conflict between your double handed ax attack and your dueling fighting style that requires one handed weapon. You might reconsider one or the other.
