ToME: the Tales of Maj'Eyal

The halfling hermit says "I'VE JUST GOTTEN MY EARDRUMS BLOWN OUT BY YET ANOTHER BY-THE-PYRE POTION GONE SOUTH, REMEMBER? " What does "BY-THE-PYRE" mean in the context?

The "Age of Pyre" is when a lot of the stuff in the lore happened. I don't want to throw any story spoilers in.

It means he is deaf.

It's an intensifier. You could read it as equivalent to "BY YET ANOTHER DAMNED POTION GONE SOUTH, REMEMBER?", but more Maj'Eyal specific.

I see. Thank you very much.
