The ink trader used to be the center of every glyph maker's business. Now that the traders only take the somewhat more expensive Blackfallow Ink, they're mostly used as a way to create more Inferno Ink. I also sometimes use them to trade Blackfallow Ink in for lower-level, common inks when I need them for glyphs, but that's only when my stocks of old-world herbs dry up. So far, actually, it's been only Ethereal Ink from Outland.
