Once, there were two children who didn't know the other existed. Little did they know that soon, their fates would collide and take them on an epic journey. Reese was a thirteen year old child that worked on their farm. Out of curiosity, they climb down Mount Ebott. Armed with a silver scythe and chain necklace, they are ready for anything. Breya, an eleven year old girl was the obedient daughter of the ever-busy principal and chief of police. When she gets dared to go down Mount Ebott, she grabs her big, worn, black leather jacket and shovel. These two polar opposites meet and go on a life changing adventure. But will they survive? **Undertale belongs to Toby Fox** **Still looking for a related cover** **Characters belong to @princessa1214 and @WriterSpeller**

Say hello to Cinnamon Dreemurr, the daughter of queen Toriel and "the magnificent Sans". This story takes place in the undertale au Underswap. Cinnamon is the princess of the underground, and isn't quite happy with her life. She has hit the age of 14, where she must find a husband to wed. Cinnamon is not happy about this. For one reason, she does not feel marriage to be necessary, for she has to wed a man she does not love. Her father Sans does not think his daughter must marry at such a young age, but Toriel said it has been a rule for the royal family for generations. But this generation, that rule is about to change... Cinnamon meets a new monster she loves, and at the same time the human falls to the underground... (Note this does include Underswap SansXToriel, if you do not like this ship, please, PLEASE, don't read)

Entry Number 63 ............................. "At 3:29pm, the barrier broke." "The monsters don't seem to be hostile, once they knew I wasn't a threat. But I'm guessing they could so some serious damage." "They didn't seem to acknowledge the fact that I wasn't going to let them leave the permitted area. Some were oblivious to it; while others didn't mind." "Except one of them." "He seems... interesting." "I'll have to keep my eye on the shorter skeleton." "sans." «~~~~~~~~~~«««««°°°»»»»»~~~~~~~~~~» Your a scientist who works for the company 'Pental Science" and you look over Mt. Ebbot, reading, researching, experimenting. Until the barrier was finally broken. The monsters aren't aloud to leave, so you'll have to live with the monsters for a while, until the company figures something out. And to top that, the monsters and yourself have rules and regulations to follow. But what happens when those rules are broken? «~~~~~~~~~~«««««°°°»»»»»~~~~~~~~~~» « I don't own any of the Undertale characters or art work » «« Next update: NO CLUE »»
