It all depends on what the DM's intent is. Sounds to me like this is some kind of plot device. If it's not but is just a "Mwa-ha-ha, I just wiped out your village!" thing then, yeah, it's time to start looking for a new DM.
But when you ask how he did it and whether it was legit, that's something he doesn't have to tell you until your characters have a way of knowing. And maybe you'll never know. But to destroy something the PCs have worked hard for in such a simple and routine manner is something that a good DM won't do lightly and will have a good explanation for (which you'll usually have to adventure to find out).
