Rtte runic alphabet
Hello everyone, ive recently started my own book of dragons, and have run into a slight issue, the alphabet i am using, (the one from rtte) does not include the letters J and X. This is quite an issue considering some dragons (timberjacks) include these letters.
Does anyone know if the letters do actually exist and are not mentioned in this? As i cant really restart the language, as im 9 dragons in already.
If not, what do you suggest as an alternative
