STOP!&nbsp THIS is what you do:
First get all the mats:
1x Blood of Heroes (found in certain spawn points in the plaguelands)
2x Large Brilliant Shard
1x Pristine Black Diamond
THEN get the quest 'Elven Legends' in Feathermoon from Sage Korolusk.
This is SIMPLE: 1. Enter DM north Library, inspect the bones, then talk to the bones/ guy next to bones. 2. Return and turn in Elven Legends in Feathermoon. 3. Return to DM Library and talk to the guy beside the bones again and he gives you THREE Libram quests, one being for Rapidity.&nbsp As you have the mats, turn in the quest and get the reward Arcanum of Rapidity.

I did this quest TWICE within 5 minutes of each other.&nbsp As you can only have 1x Libram of Rapidity (that book), you need to mail one to yourself from another toon.&nbsp As soon as you get the first Arcanum of Rapidity, get the quest again from the same guy, the go to Feathermoon mailbox and get your Libram of Rapidity, return to DM Library and turn it in to the same guy.&nbsp Just be sure to have 4x blood of heroes, 4x large brilliant shards, 2x Pristine black Diamonds.&nbsp Thats all you need to do - you DO NOT need to go to ZG!&nbsp But you will have to get the Blood of Heroes in Eastern Plaguelands youself as they are soulbound.

The corpse can be found in the center of the Dire Maul library, which you can sneak into via the North entrance, by Lorekeeper Lydros.

Upon completing this quest, the next time you visit Lydros you will have access to his Libram quests:
Libram of Focus - https://classicdb.ch/?quest=7484
Libram of Protection - https://classicdb.ch/?quest=7485
Libram of Rapidity - https://classicdb.ch/?quest=7483

1. find the bones
2. talk to the ghost of kariel winthalus, should be near the bones
3. go back to Runethorn

the text "...go to Korolusk..." she tells you is wrong. dont listen to it )

The quest starts with Scholar Runethorn. She paths around Feathermoon Stronghold. This quest must be completed to turn in Protection, Focus, and Rapidity Librams.
