Rat quest is is cool idea (it keeps the tradition) I imagine such quest: Someone is missing, the quest-giver tels us the rats are responcible for this. He dont know where they are ( you must find them/ investigate) Nobody believe on this guy, people laugh on him. So you investigate, spot one rat and it run away. You follow it to an old abandoned house. Go inside and goup of rats attack you. Before to kill the last it run back in his hole. You are curious how fiew rats kan kill a man and continue investigating, you spot that the hole is much bigger for the ordinarry rat, but not enough big to make your way in. You start searching for a hidden places. You find weak place in the wall, break it. You find your self in old abandoned and sealed area, fight fiew rats and explore the place. You find a catacombs benith the house and go inside. Fight lots of rats and in the end of the location find the The queen rat. with size of a sheep You kill the beast... ( In cases you have more than 18 wisdom you will be abble to make a conversation wit the monster and to understand that it is cursed wizard (one of the best possible companions in the game) and you can probably help hem... this is other epic quest And in the end you understand that the rats are not involved in the case with the missing man. You intimidate the quest-giver and learns that they was friends and had quarreled... probably another quest...
