Sample Adventure Proposal

The Sword and the Fallen Angel
Type: Small adventure with potential recurring villain.
Adventurers:
4-6 Adventurers from 2nd to 3rd level.  Encounters are given based on 4-5 2nd Level, but can be scaled to match numbers and levels as indicated.
Summary:
The adventurers are recruited by a local church of Helerion.  Their patriarch, a middle aged Paladin, has disappeared.  However the church priest cast a divination and learned that Sir Roderic was killed en route his return to the chapter house and his holy sword was taken by the goblin raiders that most likely have ambushed him.
Sir Roderic was entrusted with the fine weapon and he even bonded with it.  The ancient sword is of special value to the church and they are willing to pay 1000gp for its return as soon as possible.  They are afraid that the goblin bandits will disappear before the church’s knights are able to answer the call and recover the religious weapon themselves.
The party is given directions to a ruined keep where these goblin raiders are rumored to be camped, using it as a base of operations for their raids. Sure enough the adventures find the goblins easily, and battle ensues with them and their goblin dogs.
Big Bronk, the leader of the raiding party, is a bugbear that sold the sword to someone more powerful than himself.  The half-fiend woman, Narissa, dispatched a Githyanki sorceress, Zarneve, to complete the transaction delivering the bugbear’s final payment in gold, gems, and a silver holy symbol. The adventurers must face these two inside the keep but they won’t find the sword.  They will be able to learn the location of where the other Githyanki are located however.  The sorceress has a religious signet ring that matches an abandoned temple back in the city as well as the valuable looking holy symbol given to the bugbear as payment.  A successful knowledge religion check DC15 will reveal this fact, and a successful knowledge local will identify the location DC15. If checks fail, the adventures can always inquire back at the city from various places and learn the same information with a success gather information check DC15.
However, unless they capture the Githyanki sorceress alive, they will not know that she already sent the relic to her master.  So the party will likely search the underground storeroom and encounter the gray oozes occupying the room.  The sword will be discovered missing at that point.  Of course, any kind of dialogue (like interrogation) with the keep’s occupants could reveal that Narissa should now have possession of the relic.
Traveling back to the city offers the adventurers the opportunity to rest up and shop to better equip themselves before tackling the true villains.
Narissa and her Githyanki minions are hiding in an abandoned church just outside the city.  The fighters will defend themselves to the death, while the half-fiend is away. After the last of her guards are killed, she will be returning.  The players have 10 rounds to find the sword and conduct any recovery before she slips in through the hole in the roof and remains hiding in the ceiling rafters to assess the situation.  After a moment when she ascertains that the adventurers are there to recapture the sword she will reveal herself and attack trying to inflict as much damage as possible.  However, once she is wounded enough she will cast darkness and flee through a hole in the roof to escape.  The sword is hidden in a secret compartment in the alter; Search check DC20 to find. If they are able to complete this in less time, then the Narissa will attack before they can exit the building.
The adventures can then return the relic to the church for their reward.  The sword is only a masterwork quality weapon is sold or kept by the party.  The church will bond it to another Paladin to unlock its magic powers so they are willingly to pay more than that for its return.
