So you still don't understand the relevance of bringing up a lack of half-breed templates for axiomatic and anarchic creatures in a thread about planetouched axiomatic and anarchic creatures? I'm really not sure what else I can say then - I've made my point as simply as I know how; if you still don't understand, there isn't much I can do to help you.
You've read all what you've quoted and think I subscribe to 'simple'? Elaborate as much as you can. I'm the kind of guy who understands that better. Sorry, my... khm... "Sense Motive checks"
are laughable, there is no denying that. I need an explanation to be convinced, not just the conclusion of it. Admittedly, this makes it harder for you, so I'll bite and explain my thoughts on the topic, disregarding dead ends:
My original questions were
1. Who are the ancestors of the Zenythri?
2. If not known, is the lack of knowledge intentional on the writer's part?
To which your answers were:
1. 'there never were half-axiomatic and half-anarchic templates the way there were for half-celestial and half-fiendish',
2. 'There were templates for full-on axiomatic and anarchic creatures, and as mentioned above, there were races for lawful and chaotic planetouched.'
3. 'if you wanted a half-blooded creature of law or chaos, there were no (official) options to be found',
4. 'If planetouched are the
descendants of a specific kind of Outsider and a mortal race, then at some point between them and their Outsider and mortal parent, there was a half-breed, with the corresponding template', and
5. said template "was never given for lawful and chaotic creatures', which more or less carries the same point across as the first and third statement, though there are differences.
Now explain what and how the latters have anything to do with the formers. Because I don't recall looking for half-creature templates. The fact that there aren't any couldn't bother me less. Why would I care? Just because they are related? That doesn't mean it has anything to do with the topic. By that logic, I could talk about butterflies when the OP ask about whirlwinds. I'm looking for the parent race, not the second step. Since nobody knows who are the Outsiders the Zenythri claim to descend from, I'd dare to suggest there aren't any halfies around anymore who openly waltz around the streets. Obviously, if there is any of those, alive, they are just as hidden/obscure/reclusive as the parent race, or we could just ask them who their parents were.
