The three quests are:
first) on the west side of the town there is a guy with a foul smell curse ,you need to go to the cave in the most north-western in the map enter a cave and get a brooch from a naga guy that belongs to the first guy.After returning the broch you need to wait some time before returning (i did it after doing another quest but not sure if u can go immediatly) and find his front cabin empty and door open ,then *** scene and as reward you get brotherhood emblem
second)a knight is positioned just as u enter the snowy fields,he asks to send a message to a guy with a curse that lives in a capin on the lake on the eastern side of the town,after talking with cursed guy u get a horse and some armor to bring back to knight guy and you will be tasked to killing every enemy as the dude just rides his horse(the enemies do quite some damage so u need either potions or high stat equipment at this point).after finishing the murder spree return to the cursed lake guy u get another ***scene and by talking again u get a fox upgrade material
third)(u must have the lion for this not sure about other animals)u need 4 "objects" 3 found in the desert:a cow, a pig(u need lion swipe the rock hes on),and a goose;the forth is a grinding stone in a tree in the forest near the "dark forest"(lion swipe again);when u got everything u need to follow a guy aroun the world and give him an object each time and he gives u stuff in exchange.I am not 100% sure if it goes like this but :
east town exit trade cow for potion
at lake trade pig for some armor? or coins?
at the mountains behind the castle trade goose for bow
in the desert u need to escort him to oasis setelment and then trade grinding stone for life orb
in the end u will find him in a lonley lumberjack cabin on the wester side of the river west of town where u get the *** scene and the lion upgrade material
