This is called Aksara Carakan or Caraka or Coroko. It is not alphabet as like in roman writing form, but it is like Japanese or Chinese characters.
There are twenty basic Syllabaries or Characters:
- a, na, ca, ra, ka
- da, ta, sa, wa, la
- pa, dha, ja, ya, nya

- a, na, ca, ra, ka means There are messengers
- da, ta, sa, wa, la means Both are fighting
- pa, dha, ja, ya, nya means Both have the same powerful magic powers
- ma, ga, ba, tha, nga means Both are died
Aji Saka defeated Dewata Cengkar King and rule the kingdom peacefully. Aji Saka remembered his keris one day, then he ordered Dora to meet Sembada to asked the Keris. Dora went to Sembada’s place to ask the Keris.
Aji Saka forgot that he had ordered Sembada not to give the Keris to anyone. Dora had met Sembada and asked the Keris. As a faithful servant and student, Sembada did not give the keris to Dora. However, as a faithful servant and student too Dora must do what had been ordered by Aji Saka.
Both were fighting. Because both had the same powerful magic power, then they were died together.
Aji Saka was waiting for Dora and Sembada. It was too long. Then, Aji Saka delegated his servants: Duga and prayoga to go to Sembada's place. Both went there, and they found Dora and Sembada died. Both came back to Aji Saka and told what had happened. Then Aji Saka remembered what had he said to Sembada when he entrusted him the Keris.
To perpetuate this incident Aji Saka arranged twenty characters to represent his regret. These twenty characters are known as Carakan.
