I'm working on a setting in which exists this cabbal of forgers that can work metal with the power of their mind in secret rituals that no man outside their circle can even imagine. They are known for creating strong and marvellous metals, like bronze and steel, and other much more misterious and expensive, like the selenite, a strong metal of a beautiful pale blue color.
Now, these guys embelish and create these legends about their work so they can appear as powerful mages able to create super-metals, but in reality they are just good at creating high quality alloys and add some nice color to them so it can look more miche and unique. My question is, what metals should they use to obtain a metal like the selenite? Such metal should be:
- As strong, tough and flexible as high-quality steel (even more so, although I believe that's not really feasable).
- It needs to have a pale blue color, and it can't be added as a coating.
- It needs to be fit for sword crafting.
- In a perfect world this metal would be also pretty light, but I guess I'm starting to ask for too much, so I'm willing to sacrifice this point and even accept it being slightly heavier than steel.
Maybe an alloy of iron, carbon and some cobalt could do the trick? Is it even possible to have such metal?
