Just got my copy of Kings of the Sea by mail...

So it's me again with a newbie question.

both cards say: 'After a player wins X that player ...' ... don't hit but that means it doesn't have to be the player owning the location, does it ?!?

also both cards say: 'that player kneels all copies/cards...' so that means kneeling also the opponents' copies/cards, right?

Thanks for your help (in advance)... and forgive me, I am but a learner...

You got that just right. The player who wins initiative (whoever it is) has to kneel all copies of Bay of Ice in play. Same happens with Kingdom of Shadows when a player wins an intrigue challenge.
