First of all, I had never heard of Backara until now, so add me to the "Haven't heard of it" group.
So far, I really haven't found anything of interest or utility in the eZine. It seems very mundane, suitable for a more realistic medieval campaign. However, even then, it doesn't have terribly much in it to inspire a campaign or an adventure.
The goblin article showed promise, and they are interesting variations, but I think you need to rethink they're stats a little bit. First of all, you are using d6 instead of the standard d8. You are also missing their ability scores. Also, a CR 4 for Mortans? They average 12 hit points, do a little bit better than average damage, have fairly unremarkable saves, and have a mild paralytic poison (which also needs to be revised using the DMG). I'm not sure what would justify such a large CR.
Aserial the Half-Fiend/Half-Elf is....well...uh...he's a Half-Fiend/Half-Elf! Really not much meat on this NPC's bones, other than a brief mention of a spell that got him to this state. And yet he's an epic level character! Also, is Magi different from Wizard in your campaign? If not, you should use the d20 conventions of Wizard or Wiz. I haven't checked his stats throughly, so I can't tell you how accurate they are, but for a character who you say is going to be important to the campaign, he's got a rather dull history.
The remainder: Backaran Laws, Cistrean College, and a guide to measurements in the realm feel like filler material. It's very uninspired, and not something that adds to my campaign. Maybe in a more realistic or gritty campaign, but even then, where is the hook to provide interest. It appears that you want the material to be taken very seriously in a historical vein, yet there is a definite lack of depth.
The college, in particular, is very incomplete. I have a good sense of the layout of the college itself, but I know nothing about their aims, leaders or rivals. What benefits does one get by joining the college? What would I expect my duties or tasks to be? Is this strictly for NPCs? If not, is there a Prestige Class tied to it?
Finally, it's been said before. The grammar is incredibly bad. It's not one or two errors here and there. You only need to read the first few paragraphs to find mistakes, and they persist throughout the entire document. Get someone to edit it ASAP!
