Chrono-chair

The Kift's Amazing Confabulating Chrono-chair, also known as the Time Machine, was one of Professor Hamilton Kift's inventions.

MediEvil 2
Sir Dan first learns about the Chrono-chair after he receives a poster showcasing it from the Spiv. Dan confronts the Professor about it who reveals that the Chrono-chair never worked and is currently exhibited at The Museum. Motivated by Kiya's death, Dan heads there immediately. He gathers the Time Machine Pieces to repair the Chrono-chair and then uses it to travel through space, landing in the sewers. There he steals the Time Stone from the Mullocks he had previously helped. Finally capable of travelling through time, he returns to Whitechapel moments before Kiya's death where he successfully changes history.

The Chrono-chair is not seen again until after Lord Palethorn's defeat when it appears out of a wormhole. Dan and Kiya hop aboard and travel through space and time once again.

MediEvil: Fate's Arrow
As Dan and Kiya are travelling through time, the Chrono-chair seemingly malfunctions. Its turbulence separates Dan and Kiya who are thrown into their respective lifetimes. The Chrono-chair is never seen again.

Many years later, scholars would study the Professor's blueprints for the Chrono-chair but would never find it in his collection, oblivious to its fate.
