Say, what does that seemingly innocuous spell in Rudyom's catalog do, anyway?
Oops...
The ferryman is still alive as well (since he's not technically an NPC) but he doesn't have any special dialog for the Armageddon event, so it's a bit pointless to talk to him.
Ultima 6 also had the Armageddon spell, but its effect was slightly different - all NPCs on the planet (sans the Avatar and LB) vanish and Lord British goes catatonic. It also disables the ending, preventing you from winning the game.
