 camp.m18.story = Marshal Gerold the Unbending sits in his lava citadel, a paladin who has never bent anything - not his knee, not his opinion. | His gate guards the road to the Grand Master. Break it. Gerold will try to break you first.
 camp.m19.title = The Last Watch
 camp.m19.story = Three keeps hold the last shards before the citadel. The Order has thrown everything it has left into them, including its last good mood. | Take all three shards. After this, only one old man in shiny armour stands between you and your core.
+camp.m21.title = The Neighbour
+camp.m21.story = Bad news, master: we are not the only darkness down here. Mossgrim the Mouldy has dug in to the east - a master who smells of wet cellar and calls it ambience. He has heard that a broken core is cheap to take. | His creatures wear green, his floors grow fungus, and his core glows like old cheese. Destroy it before he destroys yours. And somewhere north lies a little island with treasure - bridges, master, bridges.
+camp.m22.title = The Chained One
+camp.m22.story = The knights have walled up a cave to the north and chained an ogre inside, a nasty, strong, wonderful ogre. They forgot to tell him why. | Dig into the cave and claim it - the moment our ground touches him, he will break his chains and owe you everything. Then take the shard in the east. Another sealed cave to the south is said to hold gold.
+camp.m23.title = Lady Nightwell
+camp.m23.story = A letter, master, on black paper, scented with lilies: "Dear broken one, your shards would look lovely on my mantelpiece. Yours, Lady Nightwell." | She lives beyond the river in blue halls and is twice as clever as Mossgrim, which is not hard. Cross the water, break her core and take the treasure island on the way.
+camp.m24.title = The Mana Springs
+camp.m24.story = Old mana wells up on three islands here - raw power of the deep, wasted on fish. | Bridge over to them and let the imps claim every spring: each one gives you mana for ever and lets you store more of it. The knights in the east have noticed too, so be quick.
+camp.m25.title = Mossgrim's Revenge
+camp.m25.story = Mossgrim is back. He has rebuilt his core, grown a new beard of mould, and - this is the worst part - made a deal with the Order: their gate opens beside his halls. | Two enemies who also hate each other. Let them bite one another, then break Mossgrim's core for good.
+camp.m26.title = Nightwell's Island Fortress
+camp.m26.story = Lady Nightwell has withdrawn behind a lava stream and sends her finest creatures out to deal with us. Her letters have stopped being polite. | There is a mana spring on an island in the lava - take it, it will help. Then cross over and end her ambitions. With her core.
+camp.m27.title = The Sealed Depths
+camp.m27.story = The Order buried its most dangerous prisoners down here, in sealed caves: a chainbreaker and a gargoyle, and a vault full of their own confiscated gold. | Free both prisoners and claim the two mana springs on the islands. Somebody had to find them. It might as well be someone who appreciates them.
+camp.m28.title = The Pact of the Masters
+camp.m28.story = Mossgrim and Lady Nightwell have stopped hating each other. Well, a little - just long enough to come for you together. Green to the north-east, blue to the south-east. | An island with a mana spring lies between us. Hold it, then break both cores. They will not stay allies for long, but neither should they stay alive that long.
+camp.m29.title = The Ember Islands
+camp.m29.story = Lava islands, master, with springs of mana boiling in the middle, and a sealed cave where the knights chained a young wyrm. Young wyrms have short tempers. Lovely. | Free the wyrm, take both springs and the shard in the keep beyond the fire. Then the road to the Grand Master is open.

-camp.m20.story = Grand Master Valerian Brightshield waits in his citadel beyond the great river, with the last shard and the gate of the order. He has prayed, polished and prepared for a hundred years. | Destroy his gate, take back the shard and make your core whole again. I will be right behind you. Well behind you.
-camp.epilogue = The last shard sinks into the core, and the darkness breathes again. Somewhere above, the Order of the Lightwatch is writing a very long report. | Crookfinger has made tea. You are whole, master. The underworld is yours.

+camp.m30.story = It happened as I said: your core is whole, and now everybody wants it. Mossgrim and Lady Nightwell march together, and what is left of the Order opens its gate one last time. | Destroy both master cores and the gate of the order. After this the deep has exactly one master. Guess who. Hint: not me, I am the tea man.
+camp.epilogue = The green core crumbles, the blue one goes dark, and the gate of the order falls silent. Somewhere above, the Lightwatch is writing a very long report, and Lady Nightwell's letters have stopped coming. | Crookfinger has made tea. You are whole, master. The underworld is yours.
