Babylon 5: Where are they now?

This November it'll be 20 years since Babylon 5 – not counting spin-offs – aired its final episode. A show with a fanbase as devoted as any of your Star Treks or Doctor Whos, Babylon 5 was a thrustingly ambitious space opera (its creator famously called it "a novel for television"), created and written almost entirely by one man – J Michael Straczynski. But what's happened to the main cast since it signed off on 25 November 1998…? (Just to warn you, the answer, as often as not is "they died").
