There is this sleepy little Troll village in the mountains. One day a long time ago guests began to arrive. They carried packages wrapped in ribbon, and they carried themselves dressed just as well.
“Who are all these people?” The Trolls thought to themselves. And the Troll elder said to them “They are my guests. For this day we will see a wonderful thing happen in our village.” At these words all the Trolls gathered around to listen more intently.
“It is a custom with all the living to celebrate a marriage. And we all love a good marriage party. But these Undead are different. They take a moment to make promises to each other before they party.”
“Instead of letting their hair down and starting the marriage with days of dancing, like we do, our Forsaken friends get dressed up in their finest clothes and stand in solemn attendance. Only after the vows are made does the dancing start.”
Then the Elder instructed them “Receive our guests, go an light lanterns, and set the picnic tables with food. For though the sun is high now, I dare say the party will go well on into the night.”
All the Trolls did as he said, because they all loved a wedding.
