Crownfall - Curse of Circles Haunt [GM ONLY - Spoilers within!]

[Totus Gnarus]

I've got a question regarding one of the encounters in Crownfall. Players, this isn't for you.

Spoiler:

So I've always been a bit confused by haunt statblocks. The Curse of Circles Haunt, encountered in area C19 in Part Two of Crownfall, states that 'bloody circles quickly appear on the walls and door of the hall. Anyone studying the circles intently for more than 1 round, or anyone touching the circles,' triggers the haunt.

I can quite easily wrap my head around the trigger, but what confuses me is the duration of the whole affair. The statblock lists a trigger of touch, which obviously corresponds to the description given, but it doesn't tell me how long it lasts. Given that it isn't labelled as a persistent haunt, do I only apply the effects of the haunt to the first person unlucky enough to touch/study the circles? Or is it every single time someone does so? I'm leaning towards the first, as it isn't a persistent haunt, but I'd like to hear what everyone else thinks.

I believe (I dont have the book in front of me) that the haunt affects all ceeatures within the area of the manifestation and on initiative as long as a creature remains within the hall when init 10 rolls around they would be affected. I believe my players stepped out of the hall and channeled it to remove the haunt.

Thanks, you're a champion.
