Bring Lethtendris' Web to Latronicus Moonspear at the Feathermoon Stronghold in Feralas.
The mage Lethtendris, a vicious blood elf whose brutality is matched only by her twisted addiction to magic, has fled into Dire Maul. She has created a device, a web to ensnare the magical energies of that place and we fear that, if left unchecked, she will cause irreparable damage to our world!
Stop her, <name>. Find her and retrieve her web. She is likely near the satyrs in Warpwood Quarter of Dire Maul. Bring the web to me so that its power may be released safely back into the wilds...
