A young girl named Arial discovers she is a halfling. Half witch, half skeleton. This is her story. There will be adventure, horror, and most of all, skeleton puns. Sans and Arial are sister and brother, and the first few chapters will be not that Undertale-y. I will try my best. This is my second fanfic. (other is still in progress also btw). My OC is in the place of Harry.

It's been over two years since Frisk fell to the Underground, and was adopted by the Dreemurr family. One of her former foster parents has finally noticed, and come looking for her. Now, if Frisk can't find a way to bring her families together... it might just tear her apart. Book Three of The Underground's Saviour

Sans is stuck, collapsed in the judgment hall. He is slowly turning to dust. His bro- his little pappy, has long since been dusted. If only he could do it again. If only he could fix this. (Undertale time travel, not resets.) Crossover! HP crossover to be exact. :D
