Penumbra

Penumbra is a powerful Mage and seer in Moonglow.

Her real-life equivalent is 'Manda, artist and writer in Ultima VI.

The Avatar met her for the first time in Ultima VI in Moonglow. She was grieving because her love Beyvin had died, but helped the Avatar in finding his grave and one of the Runes. Despite her posture as a charlatan (being clever and subtle about requiring more and more gold) her crystal ball gives the Avatar a unique insight into his future adventure.

After the gargoyle war, she received horrible visions of the Guardian. So she put herself into a magical sleep, to awaken when the time was right, locking her house with a special spell.

In Ultima VII, the Avatar managed to solve the puzzle to enter her house and awakened her from her 200 year sleep. However, the damaged ether attacked her mind, so that the Avatar had to use four pieces of Blackrock to shield her. After shielding her from the damaged ethereal waves, she revealed the existence and location of the Generator responsible, telling the Avatar to get the Ether Ring from Lord Draxinusom. She then charged the Ether Ring for him/her, so that the magic could be fixed by destroying the Tetrahedron Generator.

Now awake, she set up shop in Moonglow again, to resume her life as a mage.
