Looking more into the Delusions section of Legends and Lore, i decided to put forth a few points on who the journal writer is. It's easy to interpret the Myth II journal writer, he is a warrior, or possibly a zerk. He can't be a Heron Guard because in the epilogue he is going to go to a tournament to try and get the honor of joining them. He can't be a journeyman because he would already be a heron. The main point against him is he became a friend to a heron who healed his wounds, he couldnt be a heron or jman because he would have healed himself. He wouldn't be a bowman because he wouldnt want to be a heron guard because he isnt a melee style fighter. Obviously not a dwarf. But he isn't a beserk either. His hometown is Strand, which is not in the North where the zerks live.
The TFL journal writer is something different. It doesn't matter who was carrying around the arm or the book, it could have been anyone. I doubt he is a jman, because in the prologue he speaks of a "mad" jman. The jman there speaks of the Cycle of Dark and Light. It seems to be common knowledge amoung the old guys, and the younger ones think they're crazy for it, and thus the young headstrong Narrator thinks that as well. Its unlikely that he is an archer because of the pumpkin farmer thing. To contradict the theory of him saying "Captain of archers," instead of a less honorary title, since all fir'bolg were archers, im sure they used the two terms in the same sense. Again, obviously not a dwarf, i have proof but not that its necessary. A strange little theory of mine, not very usable, but his grandfather used to get drunk, and Northmen like Scotts and Irish are quite often stereotyped to be drunks. So again, he is either a warrior or a zerk, as both of them could be farmers and have drunken grandfathers. Except that its possibly a Northern grandfather would be more abusive, whacking the narrator in the head, and force kids to work... Any thoughts?
