Elvyn is great hall, comming from a veteran of 3 years!
you can get some great social life in the individual halls and corridors, and because the hall is so big, all the socail events are arranged into 2 groups, the devils and saints, so there is freindly rivalry in the hall. The only niggle is the food. The dining area for 700 or so students is kinda small, and at peak times, you can wait upwards of 20 minutes to get served.
any more questions?!?
