We will start at Level 1 in the campaign. You will get all of the gear provided by class and background, or if you prefer you can receive the amount of GP provided by your class (the chart on pg 143 of the PHB) and buy your starting gear from the Equipment chapter of the PHB.
If you put your backgrounds Trait, Ideal, Bond, and Flaw in your character sheet Notes you are eligible for inspiration. Your characters history is free to determine up until you end up in this town (the name escapes you). It's hazy since then and you can only remember a few fleeting flashes from last night.
Lastly, I'm not much of a stickler for tracking your number of rations or ammunition for things like slings, arrows, or bolts. Picking some of these up from towns is adventuring 101. If you couldn't remember to do this regularly you aren't the characters listed in this story. You can track these on your character sheets if you want, but we will just assume you have them. Torches are a different story, track these, buy them in towns.
Once characters are set I'll start up the adventure thread.
