Maybe I should add a "Gift of Ishir" tech for the dwarves? This would give "crops" ( a resource that really need a name...) and maybe a throne of andarin wonder, though that seems to be of lesser need now...
Maybe skip the wonder altogether and just have the resource? Or add the resource at "Drodarin", the dwarven start tech?
Well, that's up to you. I don't have the book, so I know very little about it. But the throne of Andarin sounds
wondrous enough to me.
Anyway, I came back to tell you that the Magnamund Companion is now available at Project Aon.
http://www.projectaon.org/books.htm
Go to other material, view online/print (PDF) and choose the Magnamund Companion.
I already have the Magnamund Companion in Swedish, so I thought it wasn't much of a deal, but they have stuffed a lot of extra-material into it, from the news-letters I think. I haven't paid attention to the newsletters before, but perhaps I should look at them to see if there's anything else I have missed. I have learned a lot by reading the MC appendixes. For instance, did you know that Ilion and Halia were once a part of Lencia? That means that their capitals, Feravan and Saldor, respectively, belongs to Lencia. So, I would advice you to remove Feravan and Saldor from Bor's city-list and add them to Lencia's. If you want you could also add the names Ilion and Halia to the list. As if 36 names wouldn't be enough.
A few other things of interest:
There's a strong alliance between Ilion and Talestria. The knights of Ilion form a cavalry regiment under Queen Evaine.
The Zakhans of Vassagonia have attempted to assassinate the Grandars of Firalond for a long time.
Valerion (in Northern Magnamund) was founded by religious refugees from Siyen and Shadaki (in Southern Magnamund).
Anari is allied to Slovia, Lourden, Firalond and Kakush, but Slovia is not allied to Lourden, Firalond and Kakush.

Slovian mercenaries account for almost 70% of its army!
There are 3 kinds of Giaks: Mountain Giaks, Swamp Giaks and Szalls. It appears that it is the Mountain Giaks who are used as soldiers by the Darklords.
Two more potential MGL names are Prince Lydan of Winigen (who built Castle Taunor in Lyris), and his brother: Prince Frennen of Woeld (in Salony next to the Slovian border). They could be used as MGL for Slovia.
You can also add Winigen (in Lyris) to the city-list of Slovia if you like.
Prince Lydan (or Lyden?) was killed in the battle of Tido (in Slovia).
Concerning our Shadow Gate discussion, it appears that I was right in that the Shadow Gates in Northern Magnamund are stationary, while the Shadow Gates in Southern Magnamund tend to migrate.
Also, in addition to the Shadow Gates I mentioned a few posts back, there is also a Shadow Gate in Ikaya in Kalte, and another one in Barrakeesh.
The royal family of Sommerlund is actually Durenese!
Only a minority of the Hammerlendings seems to be Drakkarim. The others are bandits who originate from Kagorst before the Drakkarim destroyed their city (and later rebuilt it under Darklord rule).
If I have understood it correctly there is a Drakkarim population in northern Magador!
Another MGL for Lyris (and hence: Slovia) could be Hal Morkarn. He is the mercenary captain Lone Wolf meets in Varetta. During the Darkland Wars he and his men are killed at the battle of Oredal in Eldenora.
The regent list of Vassagonia I posted a while ago is WRONG! According to the newsletter Zakhan Kimah is replaced by Lhazhor, the Emir of Bisutan in MS 5060.
So this list is definitely wrong:
MS 5050 Zakhan Moudallah
MS 5057 Zakhan Kimah
MS 5057 Allani
MS 5060 Zakhan Kimah
MS 5061 Zakhan Orhman
MS 5071 Zakhan Canokash
MS 5072 Zakhan Shoualli
The newsletters are official, everything in them comes directly from the author, Joe Dever himself, so therefore there can be no Zakhan Orhman, at least not at the same time as Lhazhor. I'm uncertain about the others. I know for a fact that Zakhan Shoualli is mentioned in book 21, and Moudallah is in the Magnamund Companion of course. But this Allani dude, who doesn't even have a Zakhan title, and interrupts Kimah's reign, looks a bit suspicious, and so does Canokash. But I'm not picky, I'm not gonna complain if you include them on a GL-list for Vassagonia. The more the merrier.

All I'm saying is that Lhazhor deserves to be on the GL-list more than some of the others.
I think I have mentioned this already, but Skarn (Lone Wolf) and Ikar (Sun Eagle) as MGL for Dessi.
This has also been mentioned: Raumas and Alema, two more "city"-names for Sommerlund.
Potential MGLs for Sommerlund:
King Corel I
Crown Prince Pheron the Young (he died as an infant)
Queen Maura II
Princess Imelda
Karl Vanalund (Ogen Vanalund's son, killed by Barraka)
Lord-lieutenant Fernant (the Sommlending representative in Vassagonia, from book 21, I have mentioned him before)
MGL for Durenor:
Prince Oldar
There are Giak shamans! And they serve the Darklords in combat as battle-magicians.
The Nadziranim are not humans (this didn't come as a surprise), and like the Darklords they cannot survive outside the Darklands (this is a surprise!).
Archlord Vashna's combat stats:
CS: 58 Endurance: 88
!!!
There are 8 other planets in Magnamund's system: Torm, Bazitto, Cannadom, Plutarnis, Gordonia, Hermidos, Shuna and Ithis.
The Sommerswerd was made by the Nuomia, a race of demi-gods serving Kai in the Plane of Light.
I may have missed something now, but read the MC for yourself to see if you find anything useful.
