Im not going to be able to write the summaries in story form, due to not having enough time so, I'll paraphrase what happened.
Soon afterward, the young warrior (A Human Mercenary named Samuel), and the Gnome (a wizard named Sprawl) meet, and begin trying the exchange words when they find, that out of all there language skills combined, neither can talk to the other.
Soon after that Samuel and Sprawl meet with Hatsumi and William (the monk and scholar). As night begins to fall they chit-chat and grow to know each other, quarreling about stupid things, and laughing at other things.
Suddenly the bells in the tower at the monastary begin to ring, and the characters run quickly to the site of several goblins that have kicked down the front doors!!! The players, in the voice of their characters then said this, it made us all roll over laughing, this was their reasons for intervening. The Monk says, " I hate those who defile temples and monastaries", the scholar then says, "i hate those who defile knowledge and learning" Then everyone stops and looks at the player of the mercenary expecting him to say something as poetic and out comes, " I'm just looking for a good fight" (Hey, it was funny to us at the time) Four goblins jump out of the monastary and battle begins with the characters. Within a melee round another shadowy goblin imerges from inside carrying something large covered with a cloak.
The PC's dispatch of the first four goblins (though i believe a decent fight was put up, with at least one character being knocked into hit points). One is fried with a fire bolt spell, one has his hand chopped off with a critical strike, one has weightlessness cast on it, and is blown away, and another is beaten to a pulp by the monk.
The Shadowy goblin though, begins to make his escape while the battle is winding down, the wizard casts another fire bolt, but for some reason it seems to do no harm to the fleeing goblin (the goblin had an armor of ithan cast upon himself, unknown to the PC's). The PC's are able to catch a glimpse of a reflective metalic object coming from under the cloak before the goblin vanishes screaming, "You may have one the battle, but you will never defeat the Sons of Bal'al-Ki!" (casts invisibility on himself, and through failed perception rolls the PC's lose him).
The characters run in to check on the monk inside and find him barely clinging to life with a dagger in his chest!! They are told by townspeople that "The Sons" are a cult who worship some terrible monster, and all live at the heart of "The Misty Forest". Of course being the good people they are, the PC's volunteer to retreive the stolen goods and find out whats going on and whos behind "The Sons" (The Sons are beleived to be behind several cattle thefts in the area, for several months)
The PC's travel into the Misty Forest, a forboding and dark and obviously "misty" wood, full of thickets and thorn bushes, and rumored to the haunted. For several days they travel (attacked by suckers and one point, finding a scouting party of two additional goblins, which they made quick work of, finding carcasses of dead owl things (from a previous adventure I ran as an intro for the player of the wizard, who is new)), until at the end of the third day, the forest begins to think out and the mist turns to fog, as a slimy, and stinky swamp emerges. At the edge of the swamp sits an old shack, a small dim light can be seen coming from it through the window. One of the characters prowls up to the window and discovers an old man writing at a desk by candle light. The PC's deside it safe and casual knock on the door. The man soon answers, and is nice, inviteing them in to have a warm meal and some tea, which they accept.
The man, who never reveals his name, warns them that they are about the enter the "misty swamp" (as for my names, i had to use the sames ones that i did in the demo adventure i did for the wizard's player, i kept the cliche/non descriptive names to help him have the sense that he was still in the same game world, with the same people, places,. and things.), In the swamp lives a terrible monster that feeds on human flesh!! But he informs them that if they travel through the swamp in a boat, the monster shall not attack them. The PC's ask him how they can get a boat, and he says that he will show them across the swamp in a boat for the cost of one thing (item) of importance that they had.
Seeing the man's tattered clothes Hatsumi (the monk) hands him two robes to wear.
William (the scholar) gives him knowledge by translating a few documents for the man.
Samuel (the mercenary) gives him two candles, without he wont be able to see or continue work at his desk
Sprawl (the gnome wizard) gives him an equally important item (which i cant remember right now)
The man then uneventfully leads them across the dark, foggy waters of the misty swamp.
Arriving in the tall grass and reeds on the other side, the PC's come to a large and steep hill in the center of the swamp. They all jump out of the boat and begin up this hill. Within just a few minutes they come upon yet another scouting pary of goblins sitting on the top of the hill. Two goblins in total.
One goblin goes straight for the PC's, spear in hand, the other takes off toward the top of the hill, screaming something at the top of his lungs.
...to be continued
Thankfully at the last second before he awoke, the teams wizarad casts a powerful spell that seprates the statue into 6 different peices scattered throughout the world. An a secret fraternal order was created to find these "artifacts" (head, left and right eyes, left arm, and the Tartarus's main sword!) and keep them safe, and away from the followers of the old ones and particularly the followers of Tartarus himself.
That will expand your campaign into a dimensional campaign. Or if that's not your bag put them in the far corners of Palladium and explore lands you've never brought your group to. They don't have to be dungeons either. It can be a labyrinth, or perhaps a piece is in the Royal castle, and the king has a fondness for it and the group needs to steal it from under his nose. Just like you did a cool back story, make a story for each piece and where they ended up. That is sure to give you ideas. 
Fighting might be a challenge. Over the years any type of critter could make a home out of the place. You can always go with something like a Sphinx, or maybe the dwarf who is entombed is a mummy. Yeah dwarves don't do the whole magic thing, but what if the dwarf was entombed by enemies such as elves? Then you can justify there being magic traps. Maybe he was too powerful in life (perhaps because of the artifact) and his enemies fear him coming back?
