The Vendetta Ceremony

Undead Phoenix looked around him. He was now in an endless white space, with illusory temples floating above his head and a constant drumming sound.

"Where am I?"

"Welcome to the Vendetta Ceremony," Mongke said as he appeared before him, wearing nothing but pants. Usually, warriors participating in this ceremony would wear full armor, but he opted for this simple and rudimentary approach.

"It's you," Undead Phoenix. "What have you done?"

"I'm sure you've heard of our ceremony. Isn't that one of the reasons the Earth Emperor tried so hard to find excuses to pursue us? I'm sure you discussed this, and probably Time Eater instigated it in the first place."
