NOTE TO Franz: All of this information here in the 'Main Quest' lore pages is not known by the NPCs unless they are specifically mentioned to know about a piece of information.
So, you've got this @Signate Ring you got from a @Gnome (@Preston Radcliffe (Dead)), and you want to find out about it. After talking to @Virgil and leaving the crash site, make you way south to the nearby town of @Shrouded Hills. The first person to ask would be the gnome standing a bit to the northeast of the town well. He will ask you about the crash if you talk to him, and will be especially interested in the ring if you tell him about it. This little bastard is obviously not to be trusted, so don't give him the ring. He'll attack you for it later, but he's a wussy little gnome so you have nothing to fear. The next person to ask about the ring is @Ristezze of @Ristezze Imported Goods, right next to the blacksmith @Gurloes' Metalworkings. Ask him all about the @Signate Ring. He will tell you everything, EXCEPT for where @P. Schuyler & Sons, the store that originally sold it, is located. There's a couple of ways you can get this info from him:
Trade him Bessie Toone’s boot (found in @Bessie Toone's Mine) or the @Steampunk Portable Camera found on the body of @Isaac Zaprunder (Dead) at the @Crashed Zepplin for it. In the full game, I suggest you hang on to the camera, as it might help later on.
A charismatic, persuasive character can use flattery to trick @Ristezze into revealing the location.
The necessary info can also be found on a piece of paper in @Ristezze's back room. @Ristezze has the key. The regular methods apply: you can kill @Ristezze, pickpocket him, or just pick the lock or bash in the door in.
