The ruins are guarded by one Water Elemental. The ruins are full of watery creatures of magic. There are a few corpses to loot and to proceed, you will need to step on some Pressure Plates. The first Pressure Plate can be found in the boss chamber, between two Arcane Stone stands ( to the west). Watch your step in the boss room, as there is a trap in the middle of the room. The boss does not leave much gains, but search the body nearby and you will notice some enchanted armor parts.
