Ok then, you guys have driven out to the lake! Which is a brilliant emerald colour, btw, and remarkably still and silent for a Lanzar terrain feature, seeing as you are kinda getting used to expecting most of the scenery to try and eat you.
First thing Vasilik is doing is trying to orientate you so that you are on the far side of the lake to the Imperial camp, poitning directly towards it.

Galahad- the Commissar has diverted, and headed undernath the Guild Hall instead.
It becomes apparent to you at this point that the Lanzar Hall of Records is undernath the Guild Hall.
Ok, here is the plan.
You guys have to zoom across the river, the other person in the skiff throwing out raptor carcass behind. Not so fast that the thrower only gets a couple of chunks out, but Vasilik says "You will want to go fast enough."
Then... you have to drive like buggery through the jungle to the camp. Which means riding these skiffs at high speed through the trees. Hopefully not literally.
