Even the Red Way and the Azure Way use the Crystal, so don't be thinking that the Crystal Way is the only logical one for Laanx worshippers.
It is true that Red Way and Azure Way mages are typically Laanx followers and Crystal Way mages typically aren't, but it's also noted that people from Hydlaa are also typically Laanx followers, and Sharven is a Hydlaan. He's also a xacha, which is a typical Laanx follower. The word is "typical" but it's a guideline, not a hard-and-fast rule. So yes, there will be exceptions. The examples of followers are there to help you decide at character creation which might be a good fit for you based on what you plan to roleplay. Clearly, every aspect of your character won't necessarily fall into one slot.
If you can tell me what specifically awards Dark Way, I'll look into it.
Edit: As for Thorian, keep talking to him and PM me the responses. While you're there you might as well help me fill out his base of understanding while I fix the beer thing.
