With the aid of a homemade Christmas card, featuring my own gnomified dwarf Warrior and a Tuskarr fishermen, I popped The Question to my dearly beloved Draenei Priest (and sometimes Nelf Druid). She said yes, which was precisely the result I was hoping to get. Here's how it went down.
Sitting by the tree, I asked her to wear a blindfold for a moment. Working quickly, inspired by a Tuskarr quest, I sprinkled Swedish Fish down the hallway. Then, I removed the blinder, handing her the home-made Christmas card. On the front was a screenshot (above) of my dwarf completing the quest The Way to His Heart... and on the inside it said "Follow your heart ... and the fish." She followed the trail of gummy fish to where I'd hung a necklace strung with the proxy ring. (Since this is the second time at bat for both of us, she wanted to help pick out the ring.) And voila, I had the best Christmas ever.
