The Tasks of Tantalon
The Stinn Dungeon
Study the ropes, gears, pulleys and belts. To pull Sir Dunstable up, the lever must be moved left, to position five.
Follow the food chain. The Demon Fish eats a red fish, which eats a fish with a red dot, which eats a fish with a black stripe, which eats a tiny striped silver fish, which is shown on the flag at the top eating a fly. Flies cost six Copper Pieces.
Count the Hag-Witches, noting their hair, eyebrows, teeth and ring. Including the four corners and the one on the facing page, there are thirteen.
The Eede Dam
Trace each pipe up from the bottom to find which valves lead to each outlet. Then eliminate valves which must be closed, leaving only three open. Naming the outlets A-I from left to right, only valves 1 and 2 lead to outlet A, thus 1 and 2 must be closed. Only 2 and 3 lead to B, thus 3 must be open. Only 5 leads to C, thus 5 must be closed. Only 4 leads to D, thus 4 must be open. Only 5 and 7 lead to F, thus 7 must be open, and the remaining valves 6 and 8 are closed. Thus the sources of water to each outlet are B: 3, D: 4, E: 4, F: 7, G: 3 and 4, H: 3, 4 and 7, I: 7, and the sum of the open valves is fourteen.
The Brimstone Dragon
Carefully count each Gold Piece to find 102.
The Princes of the Ham
Use coins to represent the frog princes and Horntoads, and hop interleaving positions. Counting only the prince's hops, the total is twelve.
Search the book to find four blue orbs numbered 3, 4, 5 and 6. The paths into the maze have two, three, five and seven stars, and you cannot reach the center by path three. Thus five stars mark the correct path.
The Ting Ring
Find the Ting Ring on the test tube rack at the bottom right. It has zero stones set in it.
Fleeing, "King" Tag meets his Queen Davina and heads south to the Bishop of Eacham, who escorts them to Sir Neibling, Knight of Eacham. Follow the chessboard sequence: King, Queen, Bishop, Knight, Castle, and find King Tag hiding at Gambit Castle. The coordinates are 1, 5 thus the sum is six.
The helm-roofed tower next to a single tree is left of the center of the map. The nearby bridge is next to a small tree and a standing stone, also visible on the map. The foam in the stream indicates it is flowing under the bridge, thus "upstream" is generally to the top left of the map. The sunrise behind the tower indicates "eastwards" is generally "down" on the map. Following the instructions, by a process of elimination the tallest tree is at the bottom left. Four trees grow next to it.
Return to the Stinn Dungeon to find the correct key hanging from the top left skull. It is number fifteen.
Look back through the book for clues about Sir Duke. At the dragon's hoard, Chauncey the dwarf said Sir Beade is Sir Duke's identical twin. At Fickling Rise, the fisherman says Sir Beade was sent to the verminpit Weirtown. Comparing the statues to people at Weirtown, there are two possibilities, the knight on the horse, or the man with the axe. The introduction describes Sir Duke as bearded, thus it must be the latter, and the correct statue is number fourteen.
Sum the answers from each task to get 196. Runestone 196 is on the Princes of the Ham page. A "hunter with no bow" at Fickling Rise told you that a "young whippersnapper" was sent for "supervision". Vision will "fade with years". Search runestone 196 very carefully, with "open eyes". On the left side, there are tiny instructions to follow, which lead through a series of runestones validating each of the answers previously found: 271, 169, 175, 345, 230, 243, 215, 123, 392, 272, 777, 321, 682. Eventually the directions lead to the Sword of Justice at Windswept Moor, which gives the last task of finding the Crown of Courage. There is a crown on the last page, but as the text says, "Pretenders and fools will end their quests here." Continue to the back cover, where the true crown bears the final inscription.
