Gameguide item/location?

[Niwashi]

What item?
Normally that info is there. If it's craftable, you'll get a link to the recipe. If it can be gathered by DoL, you'll get a link to the gathering details. If it's vendor purchaseable, you'll get a link to the NPCs who sell it. If it can be a quest reward, you'll get a link to the quest(s). If it's dropped by mobs, you'll get a list of the mobs and where they are. If it's dropped in dungeon chests, you'll get links to the dungeons.

Oh, and the Libra Eorzea app for iOS & Android is another source, but I think it has the same info as the Lodestone Playguide.
