Long ago, when humans and elves still roamed the earth, a single guild of heroes was born from a time of immediate perils and imminent destruction of the planet. Their name: Prosperitas. The tale of the guild of Prosperitas is a long one, ranging from the death of Lord Nefarian to the downfall of the frenzied dragon, Deathwing. Sadly, it ended with the complete destruction of the guild, deep within the Heart of Fear. One of its members, however, disappeared without a trace.
