Legendary Weapons
This mod adds four different multi-part quests into any campaign, each leading to discovery of a unique, legendary weapon. Solve the mystery of a skeleton key. Encounter some stone spirits and win their trust (or not). Meet a legendary hunter and help fill his trophy room. Find a way to defeat an invulnerable ghost and take his treasure.
When you have this mod active, the first wilderness scouting mission in any game will start one of the four quest chains.
