A One-Round Living Greyhawk Nyrond and Her Environs MetaRegional Adventure
From the introduction:
When the church of Lydia puts out a request for adventurers, there should be heroes aplenty to answer the call. After all, with the Canon Apocrypha opened and all that nasty business put behind them, there couldn't possibly be any danger involved in helping them out one last time.
A one round Nyrond and Her Environs meta-regional adventure for characters level 4 – 15.
Characters with the Enmity of Hassirak the Tempter may get what is coming to them...
