Welcome bloodbowlers! As you may (or may not) know Blood bowl followed the races released with Warhammer fantasy. Therefore, initially there was one blood bowl team for undead which had a mixture of vampiric, Necromantic and Khemri Elements.
When games workshop split these armies so did the split occur in blood bowl and three new teams were born Khemri, Vampires and Necromantic. Instead of ridding themselves of the old team this was retained to make 4 Ghoulish teams.
Again, I’m not sure what’s happened to them now. However, vampires and the dead are tolerated if not cheered with gusto wherever they go! I’m guess Vlad and Manfred coach rivalling teams…
Out of the 4 I’m going to first look at the traditional old-world teams the undead and the necromantic.
