"No killing Goblins." So reads the sign outside of the Wandering Inn, a small building run by a young woman named Erin Solstice. She serves pasta with sausage, blue fruit juice, and dead acid flies on request. And she comes from another world. Ours. It’s a bad day when Erin finds herself transported to a fantastical world and nearly gets eaten by a dragon. She doesn’t belong in a place where monster attacks are a fact of life, and where humans are one species among many. But she must adapt to her new life. Or die.

All her life, Spensa has dreamed of becoming a pilot. Of proving she's a hero like her father. She made it to the sky, but the truths she learned about her father were crushing.

After a savage battle, the Boundary is whole again - but it may be too late. Banes now stalk the lands of Andarra, and the Venerate have gathered their armies for a final, crushing blow. In Ilin Illan, Wirr fights to maintain a precarious alliance between Andarra's factions of power. With dark forces closing in on the capital, if he cannot succeed, the war is lost.

Powerful necromancers are on the move, and the dungeon has become a battleground. Without his faithful Wisp, Cal's mind slips - he begins creating traps and monsters that go against his already loose morals. A direct threat from an unexpected force causes Cal's mind to stabilize, but he doesn't know for how long. Using every resource at his disposal, he works to keep his mind clear while he funds a search for his lost companion.

The Great A'Tuin, the heroic turtle who supports the weight of the entire Discworld, not to mention four giant elephants, swims through the galaxy day and night with the burden of being the only creature who knows exactly where the universe is going. Philosophers have long debated where this is, and are due to find out in about 2 months. Shall they worry?

Having survived the first wave of invading players, Oren now seeks to strengthen his clan. With the Breeder's Den destroyed and most of Goblin's Gorge's resources devoted to rebuilding, his best hope lies in creating an army of golems. But for that, he needs Viridium, a rare metal that can only be obtained from hobgoblin towns, where Oren and his clan of goblins are viewed as nothing more than potential slaves.

Both Cal and Dale have become stronger, each in spite of the other. The dungeon - Cal - knows exactly how much their power has increased and is working daily to become exponentially more powerful. His schemes are becoming more complex and his dungeon - his body - more deadly.

After defeating the hobgoblin threat, Oren is now faced with an even more tenacious enemy: the players themselves. His old guild have discovered his village's location and a deadly strike force is closing in. With time running out, Oren must build up his clan and recruit an army of monsters if he's to have any hope of withstanding the coming attack.
