Well, there are a few things to do there:
You get some more insights into the cult's character.
You can acquire a book on Tenebrium which might come handy of you refuse a certain other quest.
You have a vendor for Tenebrium weapons.
You can find a puzzle in a cave nearby.
You can encounter a few funny things (e.g. look around the school).

It still does look a bit as if they cut some things there, though.
Overall the whole area seems a bit static. One or two small quests might be welcome.
And what's with the teacher and the students walking around the area and right through the heavily trapped ruins? Eventually he's always lecturing to the air since his students have al been incinerated...
