Powder to the People

Powder to the People is an unmarked quest

Detailed walkthrough
When talking to Siri, a female slave working for Caesar's Legion at The Fort, she will tell the Courier about her tough life as well as her healing powder.

With a Legion reputation of good or better, the player character can get it from her. Additionally, with a minimum Survival skill of 20, she can be told how to improve the recipe she is currently using.

The player character can then return to her once a day to get some free healing powder. If she has been given the better recipe, she will give the player character six healing powders.

Behind the scenes
The quest name is a play-on-words of the phrase "Power to the people."
