Damn, that means they have the map. He gives Lonnie a nod Sildar Hallwinter
Gundren and his brothers found Wave Echo Cave. It's where the map leads He looks between all of you and explains for those unfamiliar with the name the significance: Over half a millennia ago, dwarves and gnomes who lived in this part of the world made the Phandelver Pact, an agreement to share the rich mines of Wave Echo Cave. Supposed to have not only contained countless previous metals, but also great magical power. Spellcasters came and allied with the Phandelver Pact to create The Spell Forge. So potent was the magic in the cave a regular craftsman using the Spell Forge could create magic items. In the hands of real mage who understood it, it could create wonders. Sildar sighs But you know how such stories end. A hoard of orcs and evil wizards came and the two groups, the dwarves and gnomes and their allies and the orcs and their dark magic patrons, slaughtered each other. Wave Echo Cave, as well as the mines, were lost. People have been searching the hills around here for it since. And now an unknown force behind these goblins, someone I heard them call The Black Spider, has the map to it in the goblin fortress.
Sildar nods I was only Gundren's escort to town anyway. I wanted to make sure he got there safe, lot of good that did, but I need to find my contact. He again looks between all of you, this time sizing you up I don't want to delay you, but I could use your help once we're in town. You'd have the gratitude of the Lords' Alliance. And someone else in town might have an idea of where the Cragmaws are keeping Gundren and the map.
Maria? Gundren's ward? I'm sorry, lass. I pray he can be found before the worst happens. I at least know they took us both alive, so it must be important they can talk to him.
