Well Harro is Tier V and VI area so if you want to be able to work with your logs and essence, then aid the building of Harro Wood and Scholar shops (at the former channeller plot at ice)

See Vaxans plot and theres machines at Deidrich (Dei at map) and Vanaondos as well. And at the 2 plots south of Tradecenter. Remember, the machines are for the community. *smiles*
