... I do hazard to guess, though, that alcohol was something with which Pumori was completely and utterly unfamiliar in her youth years.
However, I guess - and pretty much fear - that she first encountered it on her journeys with Bog. I can only imagine how in an unguarded moment, in one of the many bars and taverns Bog visited with her, she might have swiped an unattended jug of beer... perhaps even the Vanolose variant!! ... and drank it!
That might have been such an occasion, now that you mention it!
Come to think of it, I think I remember Nyx mentioning something about Pixies being highly alcoholic, with a Pixie-bite being enough to send somebody into Delirium Tremens. I shudder to think of the effects of actually eating one or two on such a young creature as Pumori back then - it must have been ugly...!! o.o;
