Actually. It is!
The current iteration of the Armageddon spell draws from the Ultima 9 lore, which was the latest canon addition to the Ultima storyline.
In it, the Avatar is tasked with casting the Barrier of Life "Sanct Vas Grav In Mani An Corp" transliterated as "Sacred Great Field Create Life Not Death" before standing toe-to-toe with the Guardian, his evil alternate self. The Barrier of Life is the only thing that can contain the spell of Armageddon, which is "Vas Kal An Mani In Corp Hur Tym" or "Great Invocation of Not Life Create Death Wind Time".
Sosarian Magic Theory could interpret this roughly as a great invocation to the powers of unlife to make dead the winds of time. In other words, it is an appeal to the cancellation of existence.
Ultima 6 lore and the interactions with the Xorinite wisp find that previous iterations of the Armageddon spell in scroll form were "Corp Bet Mani", in magicspeak, Death of the Little Matter. Most likely a command rather than invocation to planar destruction at molecular level.
That I know any of this makes me a sick, sad little man.
Cheers!
