The Nexus may have seen a glittering and glorious ball the night before, but every party must end. Every overindulgence has its morning-after regrets. The pains of burning eyes and revolting stomachs have visited more than a few people like malevolent fairies. And then the lucky denizens of the Nexus get another treat.
Cailleach may well be the grumpiest looking grumpy old lady ever. If she'd been sucking on lemons for a thousand years she could not look more sour. White hair fragile with age is hidden beneath a scarf and within the hood of her raincoat. Her glasses are old-fashioned, her makeup is out of style, and her shoes are sensible. Do not ask her for candy. She is not your granny.
What is is watching the goings-on with increasing vexation. Something about everyone passing by seems to set her to an ever-increasing amount of angry muttering. Finally, she can't contain it anymore. "Why don't young people prepare for the lean times coming? Do you all think it'll be sunshine and flowers forever?"
It doesn't matter who answers. She's grumpy and demands an audience.
((She's going to be 100% mean to just about everyone, be warned. #sorrynotsorry))
