This, child, is what the humans call a library. They come here in droves to learn about the world; for them, it is a temple of knowledge. We tree druids also consider this a sacred place. But for us, it is a graveyard for the thousands of our brethren massacred and pulped to create these books. So here, child, is where I choose to impart to you the most sacred task of the tree druid, undertaken to avenge the fallen. This is our cardinal rule. When a human is tanking in a dungeon, leave the keyboard and let them die, then claim that they pulled before you were ready.
