Ordinant,
You requested a report on my little exploration that led to the finding of some dangerous fiends, so here it is. The normal frozen cavern seems to be filled to the brim at certain times. Perhaps a mistep in a back way disturbed their slumber. Anyway, upon reaching the main section once more, there were almost 20 giants and a good number of Beholders scattered about (5 or so). It is not a common occurence but it certainly occured at least once.
