I have recently realised that you can make sigils in non Roman Alphabets and they’re far more elegant... as the basic nature of Brahmi derived scripts (my native one) is that they naturally combine letters into consonant-conjuncts. Up to four consonant clusters can be orthographically represented as a typographic ligature. Basically it already has a sigil system! It can break letters down to its elements to combine into new ones. Much better suited to sigil-making in my opinion. What say Asian Witches? Have you tried sigils in other writing system than the Roman?
