Not sure, there could be item around but even in DMG there is price for ring of wish (which is one time only but you can count formula easily for multiple use one and cost goes astronomical).<br/><br/>Anyways besides sending book out to print Gilbert does also these things;<br/><br/>1) He goes around Garados digging holes. Really :P. He tries find spot where is natural clay in area if locals do not know about it. Farmers may have found clay accidentally while looking good place to dig their fields. Idea is that once clay is found he goes find sand next (it could be found in river/lakes). Once he has both sand and clay he tries organize locals to build large oven and then building where you can produce bricks. I base this on the fact that Gilbert can take nat 20 once per day and he has K:nature and K:architecture and engineering ranks.<br/><br/>2) While digging holes he has send letter towards one most respectfully honest profitable merchant guild/house and ask a presentative of that house come down to Garados for business discussion and potential contract to be made. Letter is delivered by same contact who is going deliver Gilbert's book onto production. Basically he tries arrange first trade contract for Garados where they sell extend timber to outside and also arrange merchants visit Garados to try sell luxury life products to locals (and also basic goods like tools, lifestocks, spices etc).
