Kalendorf

Kalendorf, First Knight of Velyshaa encountered Susan Mendes on Vega VI, he was on the planet in order to meet with Earth Security Operative Alby Brook, concerning the Velyshaan's involvement against the Daleks. (BFDE: Invasion of the Daleks)

However, the Daleks invaded Vega VI and Kalendorf encountered Susan Mendes who saved him from extermination by the Daleks.

Kalendorf and the 'Angel of Mercy'
Together with Susan Mendes (known to Kalendorf as 'Suz', who became known as the 'Angel of Mercy'), they plotted to overthrow the Daleks as they toured the Dalek Empire making it 'more efficient' by giving the Daleks' slaves hope.

Kalendorf and Suz conspired together using Kalendorf ability with telepathy which involved close touch to communicate, an ability all Knights of Velyshaa had. (BFDE: Dalek Empire I)

Kalendorf as Commander
Following the intrusion into the galaxy by The Mentor and her Daleks, Kalendorf took on the role of Commander of the fleets against the Enemy Daleks. (BFDE: Dalek Empire II: Dalek War)

Final destruction of the Daleks
Kalendorf and Susan Mendes created a way to finally destroy the Daleks, through a psychic impulse through their command network using and channelling his telepathic ability through Suz's link with the Daleks. (BFDE: Dalek War: Chapter Four)

This destroyed almost all Dalek technology and became known as The Great Catastrophe.

Following this even Kalendorf made his way home to Velyshaa and left psychic "recordings" of all the events fighting the Daleks which would eventually be found by Saloran Haredew. BFDE: Dalek War: Chapter One)
