Try an Arcana check on the sword. I think History is one of my trained skills, so attempt that as well, looking for any markings.
The blade is magical alright; you realize, after wiping off the blood, that the blade is extremely sharp, and it bears a heron on the blades hilt. What makes you assume its magical is the fact the blade is undamaged, and judging from the way he held it, he obviously blocked whatever mauled him to no success. You arcana check the blade. (16+7) It is a Heron Marked Blade ((huzzah for custom items!))
Longsword; The enchantment cannot be transferred and this weapon cannot be disenchanted. This weapon cannot be broken by any normal means. Always sharp. Use d10s instead of d8s for damage. Critical strike at 19-20. High crit (deal an extra [w] damage when you land a critical strike). You may reroll all crit dice done by this weapon but you must keep the second roll. Crit damage: 1d12
You history check the blade... (?) But you cannot recall anything about it. Strange...
Symon hands the pouch over to Aurel and clampers back onto the wagon to keep heading onwards.
You hand the vryloka/human (as far everyone but Weston knows) the bag and get back on the cart. You start down the path again... And then your stomach rumbles loudly, marking lunchtime. It is ~1:30pm.
You start down the path and see no more evidence of what you believe was Archuther. You spend a couple of hours following the path. You come across a wooden bridge to the right and a slope to the left. The bridge is roughly 30ft off of the ground. The bridge appears to be very sturdy and wide enough for caravans to cross. It is also, made out of logs that appeared to have been knocked over in the past couple months; the wood doesn't seem rotted or aged very much.
Check the bag.
You find inside, a lot of random objects. Small, but expensive looking trinkets mostly, a book with no title, and lastly, a set of bracers. Thyra looks at the book and says it's probably his journal.
((Just to save Highmax some trouble, this is what Symon found in the bag.))
Check the bracers and the book.
You check them out as you press on. (14 + 2) They are bracers of respite.
Daily-healing: Use whenever an ally regains hitpoints adjacent to you. You or one ally adjacent to you regains 1d8 hitpoints.
You read the journal. You read, as you ride with the party. You discover he was with the Caravan you crossed paths with and was skimming along the side. He also lost half of his earnings during a shadow creature attack as he fled. The last few pages say he felt like they were hunting him, and the last few pages are his last words:
They sent a monster after me; a giant human clad in armor head to toe. I watched him rip off his own armor and I managed to get away. I'm at the top of this spire ready to fight him if he comes. He get me good with that strange weapon of his. I don't think I have much time left, even if he doesn't find me. So much for getting rich. If I don't make it, take this book to my wife, her name is S-Blood splatters the rest of the page, and the writing is cut off.
