Commoner is an Archetype, it is a special kind of Feat. A character can only have one Archetype in total. Apart from that, Archetypes are like normal Feats and may be taken at character creation or on any level up. On your sheet, mark Commoner as one of your Feats and add all Feats gained separately.
For which reason did the Inquisition decide to hire a commoner to help them ?
Perhaps he was in the wrong place at the wrong time or perhaps did he have some crucial elements that helped them in the past.
Perhaps he showed some unnatural talents the inquisitor direly needed.
Regardless of the reason, you are now following an adventure you would never have imagined and travel to places you would have never had the chance to visit.
As an Commoner, the character gains the Feat Miracle.
If his background justifies it, he also gains the ⭐ Faith Feat.
Additionally, he gains one General Feat of his choice, as justified by his background.
Note that not all commoners have this feat and the character may de facto be a commoner without having it.
