Mies van der Rooh's Father

Mies van der Rooh's father is a rabbibunny whose name is unknown. He is the father of Mies van der Rooh. During FunFrock's Reign, they both live in house in Bug Street on Citadel Island, next to Twinsen's house. After the death of Mies van der Rooh before Twinsen's Odyssey, his father kept living in the house on his own.

During "FunFrock's Reign"
Mies van der Rooh's father played no vital role. He tells Twinsen at the start of the adventure that he and his son are planning to repair his house soon, including putting a fence around the chimney. As Twinsen just escapes from his house through the chimney, he tells the rabbibunny that he is not interested any more.

During "Twinsen's Odyssey"
Twinsen finds Mies van der Rooh's father working on some works of his defunct son, among which is a map of the Citadel Island sewers. He tells Twinsen that in order to restore the map, he needs a flask of Gallic Acid, which ran out of stock on Citadel Island. After Twinsen brings him such acid, his neighbour restores the map, and finds out that it mentions a Pyramid Shaped Key, which he gives to Twinsen. Twinsen uses this key later for opening the room in which Sendell's Ball is concealed.
