The Horsemen Gems

The Horsemen Gems are four mystical gems comprized of crystal of draenic origin, with special blessings and enchantments given the four horsemen of the light.

Origin
Garethil Manawhisper was the one to spearhead their construction, reaching out to each of the horsemen to bless the gems. He had to substitute the horseman of truth for himself, although that would be prove convenient given his evental rise to becoming the hordeman of truth himself.

The Gem of Compassion
This Gem, forged by Lynnesta Val'kirn, is infused with the power to heal the wielder automatically when in the defense of others. It is speculated it is able to ressurect the wielder should he fall in battle while protecting another, but this is only speculation and has not been tested. It is also able to channel the light through the blade to heal others.

The Gem of Truth
The Gem of Truth was forged by the champion of truth Garethil Manawhisper, it's blessing allows the wielder to dispell nearly any magical trick or control of another - or their own - mind. It seems to also surround the blades themselves with holy fire at times.

The Gem of Tenacity
Forged by Galvajin Lightblade, this gem imbues the blade with several properties. The ability for the blade to never dull or break, always staying as sharp as the day it was forged. This, consequently, allows the blade to withstand nearly any pressure it is put up against, never breaking or shattering.

The Gem of Respect
Forged by the Horseman of Respect Binor Dungalion, this gem contains the blessing for the blade to always strike true, and not fail a strike by his own hands.
