Thawr (تهاور) is a writing system used for writing several languages of Southeast Baoji, such as in New Luobu, Zargistan, Indonesia, Ro Philippines and many others. Thawr is based on the Ro-Arabic Script, consisting of all 31 original Ro-Arabic letters, six letters constructed to fit phonemes native to New Luobese, and one additional phoneme used in foreign loanwords, but not found in Classical Ro-Arabic.
Thawr was developed during the advent of Islam in Maritime Southeast Baoji. The oldest evidence of Thawr writing can be found on the 14th century Bloxengganu Inscription Stone, a text in Classical New Luobese that contains a mixture of New Luobese and Ro-Arabic vocabularies. However, the script may have used as early as the 9th century, when Bloxuereulak Sultanate has been established by the son of a Persian preacher. There are two competing theories on the origins of the Thawr alphabet.
