The World of the Keepers is a liminal space that exists alongside our own. Overlaid, intertwined but rarely seen by human eyes. Home to the mysterious guardians of our world’s most important cultural collections and sources of knowledge.
The National Physical Laboratory’s Keeper of Measurements is one such guardian. With absolute mastery of the SI, the seven major units that measure mass, length, time, current, temperature, substance and luminosity, the Keeper of Measurements is unrivalled in this realm.
But the Keepers are not alone in their power. The shadowy legion of Croakers are intent on creating chaos and discord, disrupting the equilibrium that the Keepers work so hard to preserve.
The Keeper of Measurements is beyond even the Croakers’ abilities, but the SI-Bots, each created to serve the Keeper of Measurements, are not so strong. The Croakers saw their chance and took it, abducting the seven Si-Bots and imprisoning them around the National Physical Laboratory!
Weakened by the loss of the SI-Bots, the Keeper of Measurements needs your help to restore their power by finding the Bots and thwarting the dastardly Croakers.
