Last 2 or 3 of collectable World Book Day 2006 special edition add-on. The story of Maugin, the Stone Pilot, who Twig meets in "Stormchaser". Maugin is a trog, destined to change from a beautiful delicate creature into the fearsomely impressive adult termagant. But an ill-fated trip above ground ends with her capture by Deepwoods slavers. Maugin's sale to a terrifying scientist could be the end of her - but for the actions of a brave young sky pirate - Quint Verginix. BN
