Flicker

We had our shield, but it wasn't as strong as it could be.It kept flickering like a faulty lightbulb. It did this for a long while. Eventually the flickering ceased and we were left with no shield at all. Luckily, the path in forest was becoming clearer. We could now see a cabin at the top of a hill. It appeared that the residents were home. Perhaps they were friendly. Perhaps they could help.
