Obviously, Peace is an Observer. He uses all his mental faculties and the limited, but high quality, sensors on the Cyclone to, well, observe. Observation, good observation includes good reporting. So as Peace observes, he provides quality and continuous narration of his findings.
"Approximately 125 meters away is a... The sky is currently... and the ambient temperature is... etc. etc. and it is a most conducive day for an invid attack, thankfully I have been alerting the locals to said danger and I'm sure they are taking steps to prepare themselves. More so than any of the other Sentinel worlds, I believe this one might have the best chance for survival. Pure hell has already been visited to this world and they struggle on. And now back to the tree...etc. etc."
He adds to his running (and recorded) notes his recollections from the encounter with this area previously. There is a certain amount of surrealism to the whole situation. Above and beyond the other bizarre things on this world, a big physics defying tree somehow strikes him as the most odd. It is also unnerving because a giant physics defying tree is just the sort of thing the invid would like or would create in a vile genesis pit. Yes, this place does not strike Peace as a comfortable place.
Shaking of the discomfort, Peace continues his observation by canvasing any locals he can. His definition of unusual and the definition of the locals may be somewhat different, but Peace is affable enough to pull it off. Or so he thinks.
