After being banished from the Citadel by an angry Lord Kann, Snakehammer observes how the Trolls mysteriously transform a strange, green 'mud' into every tool they desire. He reports this to Lord Kann who sends Captain Daiman and a small elf search party to collect this 'mud'. Thalia is gathering tulip dust, when she observes the elves and secretly follows them into Troll territory. Daiman, Balabust and Snakehammer locate the magic mud and use it to create a huge monster, to ward off an attack by the Trolls. This "Green Golem" goes on a rampage and only Thalia can destroy it.
