In this setting, siege weaponry has advanced much faster than infantry weapons, leading to an invention of gunpowder and cannons; however guns have not been developed properly.
In an invasion of an orcish stronghold, an orc had run into the powder magazine, and the wizard decided to throw a fireball in there, causing the magazine to catch on fire. The wizard had no idea it was a powder magazine, due to a poorly placed drow darkness spell. The drow dropped the spell after the fire was thrown. The wizard, in order to save themselves and the allied forces in the stronghold, decided to encase the gunpowder with a wall of force.
Can wall of force stop a shockwave and the explosion? If so, then wouldn't it stop sound as well? What about light? (This I think so physics-ly but not game-ly, but stopping sound makes sense).
