1)  The Halleluiah Tour of Stormwind  (level 16)

Meff the tauren warrior decides the day has come for her to seek formal paladin training at the Cathedral of Light in Stormwind.  Can you give me a "Praise the Light", brother?

2)  The Light Commands   (level 8)

Meff begins her quest for paladin training by travelling to the Undersity.  (Probably not where you'd go to learn to be a paladin, but the poor tauren's desperate.  And more than a little mad.)  Takes place earlier than the Halleluiah Tour, but that story's a better introduction to Meff's character, so I placed it first.
