I'm an Archades streetear, see.
July is a non-player character from Final Fantasy XII. She is a streetear from the Imperial City of Archades. While trading knowledge along the streets, she came across the wife of an Archadian soldier.
The woman is concerned about her husband, Gibbs, who refuses to reveal anything about his past, and she asked July to spy on him and find out. July travels far to the Nalbina Fortress where Gibbs is stationed alongside Deweg.
July uses a generic NPC field model for her appearance. Another character with her appearance is the bartender Melisa from the Cloudborn Tavern in Bhujerba.
"July the Streetear" sidequest is available after the player obtains the Dawn Shard until defeating Judge Bergan at Mt Bur-Omisace. The player can take the Rabanastre–Nalbina skyferry to reach July, who is in the West Barbician zone of Nalbina Fortress.
July silently watches from afar when the party rides a chocobo up to Gibbs and learns about Gibbs's past. At the end of the conversation, Gibbs and Deweg run off and the player gains access to Mosphoran Highwaste early (although they could also circumvent blockade via Estersand). July thanks the party, and invites them to Archades where she will reward them with a Salamand Halcyon at Charlotte's Magickery, later in the game.
After completing this sidequest, July mentions that she is "off to make some inquiries in Rabanastre", adding that an Imperial "had his coin pouch stolen by a pickpocket in the market there", likely the same Imperial whom Vaan pickpocketed at the beginning of the game.
