Altara

Altara is a sorceress on Atarka fighting against the Guardian in secret.

The Avatar was told by Bishop to meet Altara in Killorn Keep. Telling her Bishop's name, she first wanted him/her to kill the Listener, a spy creature of the Guardian in Britannia. Having done this, Altara showed the Avatar her plan for a device to cut the Guardian's lines of power: Altara's Scepter. She needed some more things, to create it, having already a altered Black Pearl. The Avatar brought Altara a the egg of a Dread Spider and an Amethyst Rod, so that she could create the Scepter. With it, the Avatar deactivated all eight places of power of the Guardian on the other worlds.

Altara also told him/her her other theories concerning the Guardian's inter-dimensional powers and helped by giving several Rune Stones when seeing that he/she used Runic Magic. However, the inquisition under Mors Gotha caught up with her, and she had to flee the castle, leaving a letter to the Avatar, saying she will continue her secret battle.

Trivia

 * She is a very important person, the game can't be won without her. Accidently killing her by crashing the keep means a game over.
