Hmm, I'm not sure about making them immobile. I see why it might be effective from a gameplay point of view, but thematically it would be a bit odd.

I was imagining they'd be just useful people to have around. If you needed a temple building but all your (cheaper) black acolytes were busy, you could send a librarian (I like the idea of having them H1, I think). If you needed an E1 mage in a battle for some bizarre reason, there'd be some chance a librarian might be able to help you out. But mostly they'd be inefficient for such tasks, so they wouldn't be overpowered. They'd also be rubbish for communions if not many of them had astral, because you'd never get enough together.

Now, making them immobile would get rid of any of that flexibility, and make them quite unattractive units I think. I don't know why, I just don't like the idea of having a unit that can't move - can't flee if enemies get nearby, and so on. Still, I wouldn't rule it out, I'm just thinking aloud. If you wanted to have them immobile, you could justify it by saying that each librarian takes a vow to never leave his cloister/monastery, and will die rather than abandon it.
