The minimum caster level for the Move Earth spell is 11th. Access to a Contact of that level would be gained around 33rd level. Contacts are approximately 1/3rd your level.
You also may be friendly with NPCs of varying levels, but you cannot rely on them as regularly as a Contact. A Contact, by game mechanic, is generally always willing to help you out.
You are welcome to discuss and design friendly NPCs, but an 11th level caster would probably have better things to do.
There is a graveyard outside the city. I haven't placed it on the map. I'm thinking it's just off the map. I'll pick an exact area at a later date.
Feel free to give me any input you like on the graveyard.
