Hm. Now that you´ve mentioned it, I actually found Thief in Bleak Falls and Warrior in that bandit camp, but I decided not to write the summaries for it because they are right at the beginning.

But maybe you could write them, Thorien. 

Book: Twin Secrets

Skill: Enchanting

Location: Jarl's Longhouse in Winterhold, inside a basket in the southwest corner of the Jarl's bedroom.

Sorry about the large images- I suck at this kind of thing. :P

Should reread them first))

Yea, the Beggar book is on the table in the Ratway right before you enter the Ragged Flagon

Book: Father of the Niben

Skill: Archery

Location: Wreck of the Brinehammer, lower cargo hold, beside the skeleton laying on the bed roll

This book always confused the shit out of me. Orcs before Trinimac? I always thought it might be wrong transcription, or they just called some goblin like creatures Orcs. It´s really weird stuff. 

Good find, Capricorn. 

Thanks :) and yeah I figured they might've been like ancient goblins or ogres or something, and the author confuses them for the orcs

What we know about it, right? It can be just an origin of the word "Orc"

Maybe someday we'll get some definite concrete lore for the orcs ya know, heres hopin!
