Some additional context/details from Anna Meyer, who sponsored Darlene's development of the font:
I helped Darlene create a font featuring the famous script of the Greyhawk logo. It took awhile but here it is, version 1 of the Greyhawk Gothic font.
It is released as Creative Commons -BY -NC -SA 4.0 so you can use it for all your gaming needs as long as they are not for commercial purposes.
