I was researching volcanic lightning and apparently there's such a thing as volcanic fulgurite. Basically, when you have lightning inside the ash cloud of an eruption, if the ash and debris in the cloud is dense enough, it can be fused into pebbles of fulgurite by the lightning strikes, and then it rains back down! I think I'm going to use that somehow for the /pcgen3k/ volcanism.
I remember you have fulgurite in your lore so I thought you'd find this cool.
