Not to my knowledge, but I'd be surprised if he hadn't been.
Noonday: Us
This chapter is about what Mokole have instead of tribes. The idea is that while there are regional differences between mokole, and that gives some differences to approach, they aren't as factional as the tribes of the Garou, and their animal forms aren't as specific as the Bastet. Basically, the stupid in-fighting politics that White Wolf had such a big rubbery one for are supposed to come from your interactions with other breeds, not other Mokole, which makes sense because you're unlikely to have much on-screen interaction with other Mokole in a real game.
They start with the Gumagan, the Mokole from Australia, whose homids are portrayed as purely aboriginal. The most interesting part is the fact that they show they have some actual knowledge of how much Aus. Aboriginal myth fits the Mokole with it's Dreamtime and Rainbow Serpent, but all the Gumagan really get is a one point XP discount on buying Umbra related gifts. The Mokole have difficulty accessing the Umbra compared to Garou, so if Gumagan are Umbra adepts, they really need something more than just "Umbra gifts are one point cheaper for you."
And then WW falls on it's fucking face as it always does when dealing with indigenous people and says that Gumagan rarely have the Resources background or technological skills. Look, White Wolf. "You're from Australia, so you don't really have the option of non-australian totems" makes sense. "Your aboriginal, so you need ST permission to have computer literacy or a notable amount of money" is dumb and vaguely insulting. Gumagan get special thresholds for the Mnesis background for some reason.
Mokole from India are called Makara, there's actually a not-terrible breakdown of the very basics of the Indian caste system which admits that it doesn't do the subject justice-
But Makara have auspices based on the sun's seasonal position rather than the sun's daily position, for no adequately explained reason. Where as most other streams have seven auspices, the Makara (and Zhong Lung) have four. They talk about Sun Dice Benefits before explaining what the fuck those are. This wouldn't be a problem if Garou had something like "Moon Dice Benefits" and you could infer that the Mokole just get them for the sun, but Garou don't, so... what the fuck? Damnit, White Wolf!
Mokole from Africa (and South America) are the oldest stream, known as Mokole-Mbembe after their progenitor. As usual, White Wolf doesn't give Africa as much attention as it could rightly be afforded.
But, no, go on about how Africa has a single Stream that it shares with South America, and there are streams in each of Japan/China, India, and Australia
Honestly, Africa is a big enough place that the Mokole could come just from there, and have plenty of diversity. There's already specific history for the Mokole of Egypt, where they were part of a pact with Bubasti and Silent Striders. Given that the Mokole are almost universally PoC, I'd be really interested in knowing what they were doing during the Apartheid. Fuck, they mention several specific things going on in Africa between the Mokole and other species, and honestly Africa could easily have it's own Beast Court like Asia does. It wouldn't be terrible for each continent to have its own Beast Court, to be honest, and the fact that this isn't true is probably more to do with the fact that the non-wolf breeds weren't part of the game from the start than any actual intentional decision.
For some reason, the Mokole-Mbembe section is the section that talks about Mokole in other regions, and for some still other reason, takes time to say that western dragons are somehow inappropriate for player characters. That makes no sense. Mokole can have wings, and be large, and learn a gift for breathing fire, and the whole "sleep of the dragon" thing seems pretty in keeping with western dragons. The only thing that doesn't match up well is that western dragons are known for hoarding gold and Mokole are vulnerable to gold.
Japanese Mokole are called Zhong Lung, they have seasonal auspices like the Makara, except that auspice doesn't set a ZL's willpower, they all just have 4, and their Archid forms resemble Easten dragons, which is primarily notable in that this includes otherwise mammalian traits like manes and whiskers. They of course have some special info about how they interact with the Beast Courts, which includes being able to make changing shape harder for other eastern shifters when in Archid form. Apparently Mokole cannot take the Past Lives background? This is the first I'm hearing of this, and goddamnit WW, you need to put chargen up front, or at least refrain from putting rules info in the "Auspices, Tribes and Breeds" chapters before you explain this shit. ZLs often have Purebreed, and your guess as to what that means for a race of weresaurians is as good as mine. Like Gumagan they have specially worded thresholds for their Mnesis background. The book goes on about how ZL archid forms resemble eastern dragons, but then the picture of a ZL in his three forms has an archid that looks like a dinosaur with an impressive feather crest and some hair glue onto its chin, rather than an eastern dragon-
Seriously, it looks like Doctor Dinosaur is trying to hide from Robo in China
Zhong Lung have their rage assigned by Auspice, like Garou, which is notable, because every other stream gets their rage based on their Suchid form, even the Makara who use seasonal auspices too. I have no clue what White Wolf was doing with this fucking book, and
neither did they.
In continuing the "we have different words for everything" theme, Mokole call their moots "Gathers," which should just be the basic goddamned term, and then each breed can have a dialect guide at the back of their book that says things like "we call gathers moots," and we get a quick intro to how a Mokole will formally introduce themselves, they have a personal name, which is probably going to be something florid, like "Cinnamon in His Light," and they will state their auspice and clutch (pack). So a Mokole would formally introduce themselves as "Cinnamon in His Light, Gathering the clutch of Towers-Above-the-Kings"
Mokole are a little bit better to their human kin than Garou, but Kin are still primarily regarded as breeding stock, given to arranged marriages, but there is the possibility of Kin being considered true Mokole if they awaken as mages or learn spirit Gifts.
The book shifts back to narrative when it gets to "what Mokole think of other breeds" and it reminds me of something that's been bugging me- the book tries to give the characters natural dialects/accents, and it comes off as kitschy and ethnocentric, since it's dealing exclusively with aboriginals and Africans, and the Canadian Garou character isn't written with a Canadian accent.
There are a couple more pages, I'll finish them up in the morning.
