Istara also contains some useful metals: The [b]Steeltanium[/b] is harder than the Ferroxyde, and will allow you to build more resistant objects whereas the [b]Carboflex[/b], that is light and flexible, is a great natural and recyclable alternative to plastics since the last drops of petroleum have been used a few centuries ago, in the Aevian System. Istara's gemstones are the [b]Concentrite[/b] (yellow) that improves the properties of whatever it is mixed up with, the [b]Reversine[/b] (purple) that reverses some effects, and the [b]Silicine[/b] (blue), a semiconductor material that is used in most electronic circuits.
Of course, lots of other resources are used in the crafting system: Plants, like [b]Mandragoras[/b], [b]Cotton[/b] or [b]Fire flowers[/b], [b]Mushrooms[/b], [b]Fur[/b], or even [b]Goo[/b], a slimy and sticky material created by spiders to protect their eggs...
