So, there seem to be a lot of balance issues about whether you start with, say, a Lost Library or an Arcane Temple. I think there should be one-use spells that Also consume a point of essence such as "Locate Lost Library" or "Scry for Gold". If you don't have Gold, Farm and a Lost Library nearby right at the start I think you're severely hampered and these one-use spells would seem to make a big difference. The use of essence could hopefully also stop them being overly abusable. Perhaps even one-use spells that only work if such a resource is Not in your territory. So you can sacrifice essence at the start to make up for a slightly disadvantaged start location.
