The Earth is in another ice age and civilisation is restarting in a future so distant that the only traces left of our time are a few precious shards of glass. When the seas rose and the earth froze, much knowledge was lost. Life on Hexult is about to change, with the arrival of the new young wizards and their strong magic; the new magic they call 'science'. Sail with Aulf across the ice, through the frozen breath of the deadly Vajra crevasse and between the quarrelling isles of Hexult.
