Part 1: Trouble at Oleg's
During their travel, Oghul makes notes of the areas of interest, to be added to a map when they get a chance. For the time being, memory will have to do.
As they get closer to the Thorn river, Oghul suggests they dismount. As they come near to the camp, she points to the platform, and up, and then hushes:
"One lookout... can you take him out in silence? Approach stealthily, I can do a diversion."
The druidess looks innocuous enough, and her boisterous foal is nothing of a war mount. She could approach casually, pretending to take her horse to the water, buying just a few seconds of distraction to get the sentinel neutralised.
ooc: if you're ok with the plan, Oghul leaves her backpack behind and casually comes out of the cover, leading her horse to the water / you do the rest :D
