Kalmar

Kalmar was the leader of the rebellion against the Three Who Rule. He was a scientist. He met the Fourth Doctor and disgused their technology, he showed Kalmar the use of the scanners on the computer they had salvaged from the Hydrax. He was in favour of waiting to develop technology before attacking the tower but was persuaded by Ivo that the time was now. After the defeat of the vampires the Doctor vastly improved their technology for Kalmar in the hope with his help they would become an advanced civilisation. (DW: State of Decay)
