The celestial catastrophe of the lost survivors

Days have passed and we still haven't found a way out, to make it even worse, strange things started to happen. From food missing, now we've lost Regina due to a mysterious disappearance, we are all so scared and hungry. Days before, I and some of my teammates came across a mysterious cave while scavenging for food. It had these strange markings, it looked like some sort of prediction. We were really curious about what they meant, so we pursued an answer. Sebastian, being the smart one, was the most curious one out of all of us and sought an answer even though we told him to let it go. Days after the incident, Sebastian started acting strange, almost like he had been possessed or something. We were all so worried about him because he was the only one. He around the island (he was the navigator of the team and an explorer)and we couldn't lose anyone else so we, as a group, assigned 4 people (I Jade was also included with Ivy, Ace and Sabrina). to go and explore the cave and to look for a way to save Sebastian, going into the cave was no piece of cake it was dark, wet, muddy, hallow and eerie, the deeper we went, the more scary it was soon enough we started hearing strange noises, like whispers drawing us closer and closer to it, it was absolutely terrifying, but we knew we were doing it for our dear friend Sebastian who had already done so much to keep us safe, minutes turned into hours, and we still did hadn't found a lead, but then a minute later we finally came across the core of the cave it was small on the outside and large inside, it looked breathtaking and stunning until it did not. Minutes after searching and exploring the cave for a clue, we found something that looked almost like an abandoned tomb and as soon as Ace opened it we knew that he had made the worst mistake anyone could ever make. What we saw inside was even more terrifying than all the beats on the island. What we saw could traumatize any human who saw it, it looked like different animals combined, but somehow it also looked human more like a demon, it had hands almost like an octopus, legs that looked like a human, but instead of feet it had hoofs. Its face was absolutely disfigured. Soon after, the cave began to glow and shake rapidly, almost like an earthquake. It was both intriguing and nerve-wracking, but something even more out of this world happened. The dead monster we saw just a moment ago was gone and, before we could know what was actually happening, Ivy started panicking and saying some stuff about how she couldn't die yet ,and she didn't care what happened to us. Soon after, she said that she ran away, leaving I, Ace and Sabrina alone to fend for ourselves. I know it was very selfish of her, but it was also normal for her to act that way she had always been like that, shortly after she ran away we heard loud screaming come from Ivy’s direction so we rushed over and what we saw was beyond horrendous, we saw Ivy’s body on the ground lifeless, her eyes gouged out, and her intestines were spilling out,and there was blood everywhere, and we immediately Knew who or what was responsible for it, we ran as fast as our legs could carry us but i guess we weren’t fast enough cause while we were all running it cut up to Sabrina, we did not know at first until she started screaming for help and without wasting a second Ace rushed in and saved her then he said“ we can't afford to lose anybody else let alone you Sabrina“ from a distance he almost looked like a superhero, and it wasn't the first time his done this, his was always one to save everyone without a single thought in mind not even caring that he might also get hurt, and I admire him for that, anyway we kept on running as fast as we could until suddenly we were cornered and had no escape, soon enough the monster caught to us and for some reason it looked even more terrifying than it already was, we couldn’t run or hide anymore so we decided to face our fears and try to fight it off, but we didn’t know how, but then Sabrina remembered something she said” Guys i think i might just know how we can stop this monstrosity of a creature, I think the markings that we saw previously can help, I remember seeing something that looked like the monster and i think there might also be makings of how to stop it” at first we didn’t know what on earth she was talking about until the marking started glowing light up the cave like light bulbs and as soon, and we saw that we rushed too it, looking for anyway possible to defeat the monster, as we looked through the markings it showed what the monsters propose, the origin and how i could be stopped, it said something about something they call the “Frangarach”(Kinda like an excalibur and a glowing sword merged together)but it didn’t quite show were we could find it, can before we knew it the monster caught up to us and in the blink of an eye it ripped all of us to shreds, and we were never heard of .
