Mordroc's brother is the tritagonist of Dragon's Lair II: Time Warp and Dragon's Lair III: The Curse of Mordread. Mordroc's brother is a sentient time machine that helps Dirk save Daphne from his evil brother Mordroc. Why exactly Mordroc had a brother that was a time machine was never elaborated upon. Dirk stumbled upon the brother in an as yet undicovered room in Singe's old Castle. The brother appeared to have some form of temporal precognition as he immediately recognized Dirk and addressed him by name. He could also trace his brother Mordroc's palce in the timestream and follow. .He seems to require only water to power him as Dirk had to fetch him some in order to warp out. He was also in some slight state of disrepair as he required Dirk to utilize his sword as a makeshift control rod.
In Dragon's Lair 3: The Curse of Mordread, Mordroc's brother helps Dirk save Daphne from his sister Mordread. After the death of Mordread, Mordroc's brother and Dirk finally save Daphne as the game ends.
