I have many favorite "Pagan Community Folkstories." This is one of them.

An Eclectic Pagan Circle, of which I have been a part, once did a joint ritual with a Druid Grove. That group used the sacred well/tree/fire setup as the focus, not the four elements as Wiccans or many Eclectics would. I was not here for this, and only heard it later, the next time they visited.

Apparently, they were holding the ritual outside in an area that... for simplicity and vagueness' sake, we'll say it was on a roof, though not exactly. There were trees nearby, and they were on a level that was a little under midway up the tree, so all participants had a great view of the full tree they had picked to serve as a sacred focus. 

Well, it was a cloudy day, and right as the Druid ritual leader was doing invocations, lightning hit the tree! It caught on fire and then the clouds just opened... and the rain put it out.

I kid you not, I heard this story from multiple people who were there, and not a soul who had been present denied it, even the skeptical sorts - but that wasn't the best of what they remembered.

With lightning and fire and rain, you see, people were rushing back into the building.

All except the ritual leader.

She just kind of stood there for a moment, then turned around and looked at them, with a curious expression and a commanding voice, gesturing to the tree: 

"Where ya'll think you're going? HAIL THOR!"
