Quest:The Splintered Throne

Objectives
Highlord Darion Mograine wants you to collect 50 Shadowfrost Shards.

Shadowfrost Shards may only be obtained in the 25 person difficulty setting.
 * Shadowfrost Shard (50)

Description
The Lich King's throne once served as his prison. Kil'jaeden himself crafted the vessel of icy crystals from the twisting nether. Its sole purpose was to hold Ner'zhul's vengeful spirit.

When Arthas struck the crystal with Frostmourne, he released Ner'zhul's soul, allowing it to merge with his own. Splinters from that impact are now scattered throughout the citadel.

I shall require those shards, held only by the Lich King's most powerful servants, to seal the power contained in your blade.

Rewards
You will receive:

Progress
Have you obtained the shards of the frozen throne, ?

Completion
These should suffice,.

Speak to me when Shadow's Edge has been thoroughly empowered and I will attempt its completion.

Gains
Upon completion of this quest you will gain:
 * 27,550 XP
 * 350 reputation with The Ashen Verdict

Getting Shards
These shards drop off all bosses in the 25-man version of Icecrown Citadel. The drop rate is approximately 25-50% on normal mode, but 51-100% on Heroic mode. As there are only 12 bosses in the instance, it will take at least five weeks to get all 50 shards.
