Magistrix Larynna wants you to go to Manaforge B'naar and obtain a Bloodgem Shard from a Sunfury Magister. Use this shard near the larger Bloodgem crystals and return to her at Area 52. Completing quests for the Scryers will cause your Aldor reputation level to decrease.
Kael's magisters have refined their usage of mana crystals to the point where they can siphon large amounts of energy in a matter of seconds.
They do this by attuning smaller bloodgem crystal shards to larger, fully charged ones.
Go to Manaforge B'naar and obtain one of these shards from a Sunfury magister and use it to siphon energy from one of the larger crystals.
Return to me so that I may study the effects of the aura. Do not worry; any side effects should be temporary.
