Erin

The Oath of Kazalm (1x23)

:

Professor Esal talks to the other teachers at Kazalm about reporting to the palace of Erin's ability to communicate with Lilan with a harp, and not a mute whistle (It is considered against the law to not carry and use one as a beastinarian) and how she is able to become close to an Ohju. Esal tells the other teachers how she and Tomura also tried to use the harp to communicate with Lilan, but Lilan would just stare. Esal comes to the conclusion that the reason Lilan only reacts to Erin is because Lilan sees her as her mother. According to legends, only the Shin-Oh could command the Ohju. However, Erin can also do the same thing. Esal believes that if they report this to the palace, others would believe that Erin was able to command Lilan by using a magic trick of the Mist People, and not because of her own efforts. Also, she believes that the palace would use Erin's ability to communicate with the Ohju for war purposes. The teachers of Kazalm decide to keep Erin and the harp under wraps, and everyone in Kazalm makes an oath to protect Erin and Lilan.
