Brandy will agree. 22 and 23 on animal handling to turn the rig around and head back to the keep. Of course that only happens if the alarms are ringing on there is signs of distress at the keep. 17 on perception.
The bells have stopped ringing don't see anything in way of conflict but at this distance hard to tell
you are able to get the rig turned around but it will be slow going back to the keep as the road is all mud (considered rough terrain half movement requiring 2 hours to get back to the keep without risking breaking a wheel)
Just in case you wanted me to roll a religion check, it's a 19. Brandy says, "Although we can't tell from here about the status of the keep, we should head back and check out what caused the alarms to go off. Besides, I need to check on Sam. And maybe we can some answers about the storm and the violet hued water."
Ulwin will use his perception a 16 to to watch for any kind of trouble. Although he will offer his opinion that maybe the alarm bells could be a setup to draw us back lnto the trap, or to alert somebody that we are on our way. Whoever is doing the ambushes might have some kind of magic user to possibly cause this kind of weather.
"You may be right, Ulwin. It could be some devious plot by I am Lionheart(Leocor). I am duty bound to answer the alarm. But your advice may ring true, so we must be wise and keep our wits about us. Expect the unexpected. My friends, whatever caused the keep to sound the alarm during the storm was something of great malice, I think." Why? Because when the violet hued rain fell, I lost my connection with the divine. So, whatever is afoot, it is something we must take seriously. And if the keep is unharmed, what issue was it to travel a few miles out of the way. We could have a warm meal and get out of these wet clothes for a bit. Finally, Sam is there and I must know if he is okay." Brandy proceeds to cautiously drive the wagon back to the keep. Brandy says, "Keep sharp boys!"
You start on your way when ulwinn spots them undead rising from the swamp walking up on shore their bones carry a violet hue as the water does. there are a total of 10 skeletons 50 feet in front of your path roll for initiative 148
