Just Walking around finding a nice lil pond. You Know what would look nice there. A Couple broken boulders with a tree growing between them. Shazbot! So mote it be. As well as some additional magic like walls that dispense coal and iron ore. On/Off water fall covers a secret back door. A little nook holds a sleeping room with furnace and crafting table.
It's MaAagic! Pick out the packing wool and refilled the water bucket after installation.
