Unable to complete Main Scenario Quest

I cannot complete the main scenario quest, "Mourn in Passing." I left the Churning Mists without attuning or speaking to Alphinaud to turn the quest in, and I am now unable to return.

Time: ~4:30 am Server Time
Date:6/23/2015
Character Name: Shenzu Soze
Server: Leviathan
NPC name: Alphinaud
Area: The Dravanian Forelands/The Churning Mists

You can walk there. The entrance is next to the Sohl Al dungeon.

My spelling is wrong... But go talk to the dragon next to the dungeon.

This worked. Thank you.
