The Unnamed Sword

Look at the crystal ball son Merlin commanded.</p>Gawaine looked. Inside the shimmering ball he glimpsed a pallid young girl on a hospital bed.</p>Elli's dying Gawaine. In weeks she'll be dead. Only two ways she can be saved. One of them lies in Camelot's wilderness. You must quest for the Silver Chalice.</p>And if I can't? protested Gawaine.</p>There is another way but it's too difficult even for me to mention.</p>There seems to be more Merlin continued. I see a speck where it should be clear. A dark speck. Wait please.</p>A moment later four huge creatures that seemed a cross between a mass of writhing serpents and gigantic squash on legs rampaged the length of a village leaving nothing behind but raw earth.</p>Merlin looked hard at Gawaine. There's a second labor for you it seems. What now see are hydras nightmare creatures from another place and another time. You must destroy these hydras before they and their kind consume your planet. Yet unless you learn the name of your blade it cannot be done. And unless you save Elli you have no hope of learning your sword's name.
