After the destruction of Serpent's Hold, she and a band of warriors stayed within the ruins to protect the Bell of Courage. However, when the mage Groldek invaded the ruins at the orders of the Guardian, the others lost their courage, and they left. Lyssa stayed, and hid with the bell in a secret room.
After the Avatar had slain Groldek, Lyssa admitted, that while she was a strong Fighter, she had little chance against magic and decided to entrust the Avatar, who was more capable in that field, with the bell.
- She is also the trainer for the fifth level of single handed weapons.
