Chanterless is pretty simple, the main thing you want to do here is finish your first sidequest, and maybe level up a bit. There are a few hidden areas and some special items here that you can get as well. I'll just take you through each area marked on the map first, and then talk about the sidequest, Slaying the Werewolf.
If you go to the Church in Chanterless right away you'll find that the doors are closed and you can't get it. That's because there is a werewolf inside that has been terrorizing the town. You'll need to agree to slay the werewolf in order to get into the Church. The key is held by Chanterless' Mayor in the Town Hall, but don't go there just yet. Visit all of the other places on the map first. Also, if you notice I have marked the entrance to the Forest Maze on the map. If you try to enter the maze now, you will find out that Random would like to attempt a "practicing" quest before going on. So you'll have to at least accept the Werewolf quest before you can enter the maze.
Chanterless' Town Hall - If you visit the rest of the town
first, you will hear about a werewolf that has been terrorizing
Chanterless. Agree to kill the werewolf and the Mayor will give you the
Chanterless' Church key. The reward for killing the werewolf is a whopping
5000 gp!
The Dusty Boar - This is the Chanterless' Inn. You can rest here (for the
cheapest fee in the whole game, 5gp) or buy food and supplies. Searching
the basement will get you 120gp and you can also hear about the werewolf hiding
in the church.
"Ticking Clock" House - You can't seem to talk to the old man of the
house, but if you look near the curdled milk in one room you can find the
"Kid of the Sun" Scroll, a 1 use scroll that casts Razor Sun. An
antidote is also hidden in the house.
Post Office - If you talk to the postmaster, you will find that Sarah has
a package waiting for her from her friend in Indinera Falls, Tilsatroth.
The package contains a Sylvian Rapier, a Mirmillic Robe, and a Sea Ring!
Chanterless' Weaponsmith - You can buy various weapons and armor here.
Chanterless' Church - The church is closed because of the werewolf but you can
come in here after getting the key from the mayor.
Save Point - The girl that owns this shop will sell you drinks, or you can save
your game for 2gp. She also has a book on the counter that will tell you
how many fights each character in your party has contributed to. She also
has a Fruit Machine here for gambling, but if you try it now you will find that
it's not working.
Hidden Area H - This area holds the Dahlos de Loo sword, a fairly powerful sword
for Random and your first Relic. You'll have to fight 3 Guardians of the
Loo, but they weren't very hard and I beat them at level 2 and 3 I believe.
Mosquito Bee Nest - The first time you go to this flower bush you will find a
swarm of Mosquito Bees. Not that hard to defeat but worth the fight at the
early stages of the game.
Secret Minotaur Hideout - If you walk into this flower bush you'll discover a
secret Minotaur hideout, along with some books and maps giving you hints to
later plot developments in the game. You'll have to fight a group of Big
Cows to be able to explore here, but they are fairly easy to beat. You can
also find 7 beers in here.
Entrance to Forest Maze - You won't be able to enter the maze until you've at
least accepted the werewolf quest from the town mayor.
The best thing to do is clear out the entire area, going to all of the secret areas, buying food and new weapons, and maybe levelling a bit. After you're done with that, go see the mayor in the town hall, and get the Werewolf Quest. After accepting the quest, you can enter the Chanterless Maze, but you may as well finish the Werewolf quest while you're here. Head over to the Chanterless Church after getting the key for the mayor...
