some combination of the words:
'Behold! You stand before the Haven of the MULTI-HAG, heavy dread and sickly sweet smoke pervades the area.'
just to feel alive, y'know?
Only TTRPGs let you do that! (without people giving you the stink eye.)
something like:
'darkness gathers around you, shifting shyly, as if waiting impatiently for your fire to dim and die out'
without an eyebrow being raised in question.
