Jini is a friend of Yuria's. She acts as a go-between for Lache and Yuria in order to make sure their affair is never found out.
This is ruined, however, as she is captured by orcs while sending a message from Yuria one day. She is then poisoned by Daru.
As a result, Sieg, Eir and Dainn go into the mushroom forest to find a cure.
