Look for something that would shed some light on its origin. Any marks or symbols on the bones?
Look on the ground around this thing. Anything interesting around it? This thing wouldn't go down easily, might have more remnants around it.
The bones do have markings on them, but they appear to be something related to the construction of the beast rather then its origin. The symbols at connecting joints and parts are the same, almost like a guide to what parts to where. There are other symbols, a line of them have been shallowly engraved along the brow ridge of the skull, but you can't understand them; they're very complex though, so probably a logograms not an alphabet.
The foliage around this body seems thicker than elsewhere, more in bloom as well. As per what brought it down you can find no clues; the skull is partially buried however, so maybe whatever killed it is just hidden away beneath the soil.
((Nah, I'd rather take his knowledge and give him nothing. ))
Xankarvo looks up from the book with a sigh of relief. He immediately began scuttling about the warbeast, looking for ... something, he isn't telling what.
Do we have any paper in good condition? Look for paper.
There's no paper around. The closest you can find is some spare fabric that hasn't been used to make a giant oversized flag.
Circle the warbeast. Look for more bones.
There are other bones around here, but they they're mostly scattered, broken and inconsistent. There are no nice skeletons like the giant, but you do find a few interesting bones, including the skull of what appears to be a large bird like creature and and an intact and mummified hand clutching part of what could have been a weapon, but is now not much more than a rusted chunk of oddly shaped metal. Many of the bones have evidence of violence on them, some burnt, others smashed apart or snapped. The more you search, the more bones and bits of fabric and pieces of metal you find. The most intact thing you can find is most of the ribcage and one arm of a creature; it's quite an odd thing. The arm branches at the elbow into one thin arm with fine delicate finger bones, and another which is more or less a club of bone ending in three thick fingers each tipped with a hard, stout bone spike.
Search around the skeletal remains for evidence of structures, such as those on our warbeast. Does it appear to have had passengers?
The metal armor of the beast, whats left of it, shows no signs of external structures, but there are large holes in it that look as though they were purposefully made. Not stab wounds but doors or ports or vents of some kind. Perhaps it was controlled internally? Perhaps it was autonomous? Who can say.
Any mysterious artifacts of power around?
Nothing on the surface that you find, or at least nothing intact. Maybe buried?
