In the hypertext, I don't see anything under the magic-user heading that states that they may build strongholds at 9th level and thereby tax attracted settlers
. Is this something that is spoken of elsewhere in the hypertext or an omission (or possibly an intended situation) from the LBB from way back when? I'm just curious, as I'm not terribly familiar with OD&D even though it's my favorite variety. Remember, for some of us OD&D is something of a new toy!
