Thank you for your feedback! Yes, in retrospect using this font especially for the longer texts was a questionable decision.
The mythological side is actually pretty interesting. The target of the Prussian Crusade were the Old Prussians, a Balto-Slavic people, who later got assimilated / germanized. The had a polytheistic religion closely related to other Baltic faiths. Most of the sources about the Old Prussians were written at a much later date and introduced several major legends. The Temple of Romuva is one of them and was never actually found, neither in the real world or in the legends. It was supposed to be a holy tree with eternal sacred fire. As the name suggests it is derived of Rome and may have been a propaganda lie by the catholic church to gather support for the crusade.
