Oak Tree

Oak is a term used to refer to around four-hundred seperate species in the genus Quercus(Latin for "Oak Tree"), native to the northern Hemisphere of Earth. Historically, they have been used in a variety of ways, from ship building to wine ageing, and when the first Human colonies were started, the first settlers saw fit to bring the Oak Tree to several new planets, quite possibly for its strength and resistance to atacks from insects and fungi.

Oak Wood was brought along to the colony of Madrigal, where it was considered "very rare". Ignatio Delgado's uncle saw fit to carve the modified stock for Señora Sies out of the wood.
