Ohhh Ohhh! That's a good one!

Willem is almost certainly val'Ossan if his nanny thinks Milandir would accept him as King. Yes there is no actual ban on a non-val'Ossan holding the Thrown...but the one example we know of with Oswald val'Inares (aka the Usurper) is not exactly one you want to be compared to. No idea about Annis or Lysa. Might be strange if all were val'Ossan. OTOH maybe they had more than 4 children and the val'Haupts were quietly shipped back to Censure? On yet another hand the frosty relationship that ultimately emerged between Osric and his wife makes this somewhat unlikely. From what I've read I'm kind of surprised they have four children at all.

Which I think may be part of the question as to whether Annis, Lysa, and Willem are all val'Haupt or val'Ossan... If the latter, they're likely Osric's. If the former... there's no such guarantee.

7) We know where 3 out of the 5 Holy Pillars of Nier are found (Hunder, Erduk, and on the Isle of Ymandragore). Do we know where the other 2 are found?

8) Do the major vassal families of the Vals also display traits similar to the Vals? Do the Otrecto's tend to breed larger, more amazonian women than the average? Are the Gracchi's blond and olive skin? Do the Balins have lots of hawkish noses?

9) As Coryani Legions are not organized directly like Roman Legions (1000 troops in 10 Centuries of 10 Deciums of 10 instead of 6 Cohorts of 6 centuries of 80 soldiers), do they serve similar non-combat roles and specialties that a Roman legion did? Are all the soldiers expected to also be engineers, making palisades and other fortifications every night when they make camp like the Romans did (Ancient Trench Warfare ftw!)?

8) Unknown. But sounds reasonable to me. More an influence than a rule I suspect.

9) The Legion of the Watchful Hunter showed up in a fairly recent mod. IIRC they were 6000 strong. Much more like Roman Legion in size and scope.

In terms of the Legion of the Watchful Hunter, I'm assuming that either 1) There was a confusion about how large a canon Legion is in Coryan, as established in the Codex Arcanis (mk.1) or 2) It came with 5 additional Legions of Auxillia. Though (1) likely played a huge part in this, I would in no way be surprised if an occupation force was sent into a satrapy with a hefty reenforcement.

I'm not sure if it was confusion or not. It's clear that when a Legion is founded that the number of men is 1,000. It's not clear whether all legions must remain at that level once fielded or if that is simply the minimum number to be considered viable. The original campaign referenced the legion at 4,000 when destroyed. In the MetaOrg document that was proposed though not adopted during the first campaign a legion was proposed to be between 3000 and 5500 not including Auxillia.

A large number of Auxillia is certainly possible. It's also possible that commanding officer was a High General in charge of multiple legions marching under the banner of the Watchful Hunter.

At the very least, given the distance from the capital a larger than normal Legion would make sense.

With a sweep of his hat,

Paul

They are listed as being in Erduk, Cancari (Hunder), Khitan, Coryani Empire, and the Isle of Ymandragore.

Under the Warrior of Eternal Flame Prestige Class it lists each Flame's location in the order you were "suppose" to go through them. In the 2nd Ed. of the book with Errata they removed the Flames' locations, and stated that you could enter them in any order.
