This is the artist Tomasz Jedrusek (aka 'Morano')'s impression of the scene in The Wyvern and the Wolf where the Yamayohei ninja clan stage an attack on the fortress compound of the samurai daimyo Lord Jensu Aoyotaka.
Visible in the background is one of the book's 'Fallen Arks', an ancient megalithic wreck of one of the space-faring ships belonging to the extinct civilisation of Antediluvia.
