Volcano Cannon

The ork wall was easily a hundred metres tall. Throne knew how long it was. It was breathtaking in its scale. It was plated with great metal slabs of armour painted red from top to bottom, and decorated with oversized ork glyphs daubed crudely in white.
...There  were vast iron  gates, as tall  as the  wall itself, spaced  at intervals  all along its length, but none were open. They looked very heavy, very solid.
...
Then, suddenly, the whole bulk of the Shadowsword shook as if it had been kicked by a giant. Blazing white light burst from her cannon, lancing straight across the battlefield, striking the massive ork gate dead centre. The air shook with a massive thunderous crack. The iron gate glowed blindingly bright for an instant, and then seemed to vanish completely just as if it had never been there at all. The armoured wall all around it glowed white, then yellow, then orange and red.
