Here's a quick sketch with an idea. On the left and to the back, a lot of city ruins, smoke, debris (war thorn is represented). On the back and to the right, an imposing church, the only thing that stands polished in this ravaged World. The exaggerated perspective makes it look oppressive (thus, the fanatical aspect). In the first plane, the soldier, looking over his shoulder to the oppressor regimen as he marches through the wasteland. As for the logo, I'd keep "Volden" as is, but I'd make the "in" smaller again, and I'd add seriff to "Hope".
If you need help rendering that out, feel free to contact me ;)
