Time is complex: a mesh of constants and variables. Some points in history are, of course, fixed – but others are permanently in flux, easily disturbed from their rightful position. When Luna Fox first discovered time travel, she quickly realised something was awry. As she delved further it began to become apparent: some objects bear down upon the weave of time, distorting it with the weight of their power. These artefacts are mysterious, exciting – possibly even dangerous. Some you may remember from folklore or myth: rest assured, many are fictional – but others are most certainly real. Luna and her assistant, Babbage, need your help to secure these objects – to safeguard them from nefarious forces.
