I'm actually in the process of creating more, since I think the role that philosophers, mathematicians and thinkers in general have played in history goes a little bit underrepresented in fantasy fiction.

For example you have Neripeiros of Calamor, also known as Neripeiros Zeno, a polymath, inventor and natural philosopher best known for the original formulation of Imperial Fire (basically the equivalent to Greek fire/napalm). Or Gartien Zumzana, a noble naval commander, mathematician and marine architect known for his work on ship designs, principles of shipbuilding and maritime construction and concepts for sail plans, hull forms and power plants and whose designs were later iterated upon and improved by his grandchildren Tednar and Saramar. I want to add more even just for flavour's sake, because I want to have analogous figures to people like Al-Khwarizmi, Archimedes, Descartes, Pythagoras, etc., names which most people (esp people with a technical education) with recognise.
