Tessa

Lady Tessa is the ruler of Bordermarch in Ultima V and keeper of the Flame of Courage in Serpent's Hold in Ultima VI.

In Ultima IV, Lady Tessa could be found along with Lord Simon in the armoury of the village of Paws. She knew the location of the mystic weapons, and helped the Stranger to get them.

In Ultima V, Lady Tessa told the Avatar that the amulet of Lord British could be found in the Underworld amongst the graves of valiant warriors. She further mentioned that the amulet could light the way even in the deepest darkness, and was essential to reach the lair of the Shadowlords.

Lady Tessa along with her husband Lord Simon ruled over the brave knights of Serpent's Hold in Ultima VI. She was formerly the ruler of Bordermarch along with her husband, but when the island sank into the ocean after a massive earthquake, they became the masters of Serpent's Hold.
