D&D 3E/3.5 3.5E Holy Weapon Break DC? Effects?

[Dross]

It will turn out that the people who put the PCs up to this "free the celestials" crusade are actually a consortium of mercanes and other merchants who possess a large stock of potions, oils, wands, staves, and other expendable magic items of align weapon and mass align weapon. Their goal the whole time was to remove the supply of permanently good-aligned weapons, so that they could charge a premium on their temporary solutions.

Or put about by the demons/devils themselves to deny said weapons any chance of being used against them.
