We hang out with Canada's own Sebastien de Castell, author

of Traitor's Blade and Knight's Shadow. Talking swordplay in fiction and

history, Sebastien's musical exploits, the debut of live Celtic whistle, John Lennon

impressions, the influence of music in writing fiction, Chris Cornell, the

balance of magic and realism in fantasy, how dark is too dark in grimdark, and

the new eight book publishing deal. Find Sebastien on Twitter @decastell.
