Lightbringer

Reinforcements must move through the Shadowchasm, for it is the quickest way to Ulan Bel. We must get reinforcements to that beleaguered tower! Now that we have turned the tide in this conflict, we cannot afford to allow the tower's defenders to be slaughtered. What I must ask of you next is no small errand, but all hope will be lost without your help. You must enter the Shadowchasm and clear it of our enemies, for only then will the way be safe for our reinforcements.

Travel to the Shadowchasm. Slay six Razormist Ambushers to clear a path for the High Elf reinforcements. Return to Aliron Dragonshadow at Cinderblade when you have done so.
