When the Vampire Team was introduced (in 3rd Edition), as well as the usual blood sucking stars it included a Vampire Lord In fact, having one was compulsory at the time and while the rules have evolved since then, the background and theme was very interesting:
All vampire teams are coached by a Vampire Lord, a rather more strong-willed and powerful member of the vampire race. Vampire Lords are exceptionally intelligent creatures who thirst for power over other races. This being the case exactly why they should want to coach a Blood Bowl team is by no means certain, especially as the team under their command rarely does very well, but none the less they do do so.
All of the other players in a vampire team are the Vampire Lord's creations: vampires or human thralls. The vampires were one living creatures, which were almost - but not quite - slain by the Vampire Lord and then brought back to life as lesser vampires under his command. Vampire teams generally also include a number of human thralls; weak-willed mortal creatures that are willing to serve the Vampire Lord in return for the promise of immortality at some time in the future.
Vampire Lords are player coaches, and actually take part in the game rather than simply yelling at the players (and referee) from the sidelines. Although the Vampire Lord represents you, they must still be bought for the team, as shown on the team list below. The team will keep on functioning normally even if the Vampire Lord is killed, it being assumed that the next in line of the vampires in the team (i.e. the one with the most SPPs) will take over. The vampire that takes over the team immediately loses the 'off for a bite' negative skill as soon as the old Vampire Lord dies, and it's entry on the roster should be changed straight away to show that it is the new Vampire Lord of the team. Note that since you can only have one Vampire Lord per vampire team, the only time you can ever purchase a Vampire Lord for a team is when it is first created! If for some reason there isn't a vampire to take over the team when the vampire lord dies, then the team will disband after the match.
