Kill Grelod the Kind

That was the quest given to you by a young boy named Aventus

The rumors you heard upon arriving in Windhelm had caught your attention. Why the hell would they be so afraid and uncomfortable with a child? You understood as you entered the Aretino estate. Watching the little boy repeatedly stab his iron dagger against the human sphinx made from scratch was terrifying... but hearing his pleas, which grew increasingly tired and sad, was devastating.

Although the boy mistook you for a member of the Dark Brotherhood, you still decided to head to the orphanage the boy had escaped from... mainly to see if the accusations were true... and well, they were true after all... seeing Grelod verbally abuse the poor orphans and finding out that she also beat them was too much, but finding out that she also prevented them from being adopted was the last straw.

Finally, You did, the children were happy... Constance, not so much, but even so, Aventus was glad to know it was all over.

Even though it wasn't your business, you still went to visit the orphanage every so often to check on the children and Aventus, who claimed to be much better now that Constance was in charge.

Aventus might not have told you directly, but it made him very happy every time you visited him and told him stories of the things that happened to you during your journey in this whole Dragonborn thing...

"You came to visit!!!" Aventus's voice echoed from the bedroom as he ran towards you with an unhidden happy smile

"How are you?! Do you have any new stories to tell?"
