You can get the Shard Sword early in your quest. Find a woman in the old city and collect the three shard pieces. The green shard is in the Lenele sewers, the red shard is in the Temple Of Urath, and the blue shard in the catacombs on Iona. Return them to the woman to get the Shard Sword as a reward. The Shard Sword has great strength but a slightly low speed.
