You find martas house after defeatign dhoulmagus, then you go to the town of Ortikts (or something like that) and you end up going to this cave to find marta's son, you end up back at martas cottage and you get attacked by wolves, (that is a VERY long battle) And then evil sir leopold (also found after dhoulmagus) will Kill marta, but before she dies she gives you the ultimate key. And undefiant, I dont know the answer to yours.
Good bye everyone, it's been fun!
