Philip Bouwsma makes use of his extensive calligraphy and type design experience by reaching into his vault and completing one of his unfinished projects from the mid-1990s. The result is Styx, a four-font connected-script family, with rough and smooth variations, each containing two sets of majuscules and plenty of alternates sprinkled throughout the character map.

The Styx family comes in all popular font formats, and includes an extended range of language support covering Western and Central/Eastern European languages, Turkish, Baltic, Esperanto and Celtic/Welsh. The OpenType fonts contain both flat and class-based kerning.
