Kat,
Tony, Sarah, and I are working on a project to undermine the Spire's foundation as you asked. Right now we're in the theoretical design stage. How soon are you thinking about taking action? Knowing how much time we have to work with is valuable information.
I'll have to take myself out of any direct action at some point in the near future. I don't know if it's a result of the wish or the man sniffed out my involvement, but I'm having triplets. At the rate I'm blowing up I'll be too pregnant for helping out beyond planning or spellwork by July
if not sooner. Izzy
