ToME: the Tales of Maj'Eyal

So I'm about 10 levels into my Adventurer, and I look for the locked Wildfire tree. Except it's not there. And neither is Ice, Stone, but for whatever reason Storm and Aether is there. I could've sworn they were there when I started my adventurer.

Help?

Your adventurer can use only those trees which have been unlocked beforehand by other characters. For example, if you unlocked solipsist class, those specific trees like solipsism, feedback, etc will become available for adventurer. Have you already unlocked wildfire, ice? Because it's way more difficult than, for example, storm. You can always check what you unlocked in your profile at te4.org

Thank you very much. I feel like a complete idiot.
