Ferros

A resilient metal that is hardened by the impurities within it.

—In-game Description

Ferros is a common resource obtainable by mining red ore veins in the Plains of Eidolon. Its main use is in crafting Fersteel Alloy.

TriviaEdit

Based on its appearance and description, this is almost certainly an iron ore. Its name is likely an Orokin or Ostron nomenclature based in the Latin word for iron, which is "ferrum".
