Water Elementals

The water elementals were no doubt summoned by Gazban, the goblin wizard rumored to have discovered the Stone of the Tides. As you may know, the Stone of the Tides curses its bearer, causing him to fade in and out of existence...$b$bPerhaps we can find a way to counteract the curse. We can have a mage of Dalaran analyze the magical residue of one of the water elemental's bracers. I need you to go back to the island and retrieve a few specimens.
