@Kobold Stew - is that correct that you are running off to the East? Like down the hill toward the Kobold Lair? The reason I ask is that it will probably ruin your ruse - there is still a cultist and some Mercenaries trying to catch up that will probably see you go. I mean, I'll roll for them, so they might not notice, or think that Siobhan is just checking the other passage (though the last-to-arrive Mercenaries just ran past her body not more than 12 seconds ago, so they'd probably figure it out either way.)
Everyone is in a huge rush, though, so I'll let the dice decide. Just let me know that it is for sure what you are doing.
