Cegon

Dnd-ish type world. You joined a new guild and met with a new group. After a while chatting the group decides to go into a dungeon and fight some low level slimes. Everything was going great. You even found some good loot. Then, out of nowhere, a red slime appeared and was bigger than the rest. One of the group members tries slaying it, but it suddenly takes a human form, and before you know it, everyone in the group is dead, and you are hiding in one of the dungeons' many rooms. ♡You can be any class/race♡
