What about the Mosque, why all the christian references? It might offend some muslims.

It would be...erm...inaccurate. You would pray at a mosque, as well as study but not tell tales or discuss alternative history. Of course I mean the mosques in the high ages of Muslims; they're deathly places nowadays.

But "Medrese" (or "Madrasah" ) would be fitting. (The original is مدرسة, let the Arabic experts pull out the best transliteration if necessary. )

At any rate I would prefer a classical word (with Greek/Latin/Arabic/Hebrew origin) over a modern one.
