The current Alliance trek to Scarlet Monastery usually involves taking the ship to Alah'Thalas and jumping overboard for a long, tedious swim. While it gets people near Alah'Thalas you skip it as this method bypasses the zone rather than engaging with it.
I propose a thematic option that utilizes High Elf lore to give Alliance a better journey.
The Quest: "The Lost Liturgy"
NPC: A High Elven Priest or Paladin (Silvermoon Remnant) located in Alah’Thalas.
The Narrative: Long ago, High Elven scholars studied the Light alongside the humans at the Monastery. When the Scarlet Crusade fell into madness, many Elven relics were left behind. The NPC tasks you with retrieving an Ancient Elven Censer from the SM Library.
The Mechanic: To aid your "infiltration," the NPC tells you of a forgotten Sun-Mending Runestone hidden on the northern coast of Alah'Thalas. Once the quest is accepted, players gain the ability to use the Runestone which is a permanent one-way trip to a forested northern area of Tirisfal Glades.
