"I can't stand not being the strongest! I will become the strongest in the whole world, all of time, all of space! That is my Greed - I will consume all EXP with my gluttony!" (Ren)

"For this foolish sinner, the punishment I have chosen is consumption by God's name! I offer the power of my acquired lands to shred that one with decay, and consume!"
"Starkverfall!" (Ren)[1]
