Some folks are wondering what to do after they've done a lot of the major quests, there are a lot of other small quests that can be fun. I will list those i can remember and how to get them:
Unexpected Voyage: spent a night at teh bloated float in the imperial city
Killing Field: talk to vallus odil in the grey mare tavern in chorrel
canvas the castle: talk to countess velga in castle chorrel
two sides of a coin: talk to Arnora in bruma (might require asking about rumors in bruma)
Fines: talk to people in cheydinhal about rumors
order of the virtuos plood: visit the temple district in the IC a lady should aproach you.
unfreindly competition: talk to the merchants in the IC
Muzoga the orc: talk to count of layawiin
Bear problem: talk to a farmer in a hamlet north of kvatch
Paranoia: glarthir will aproach you in skingrad (not much point to this one cept some septims)
all female gang: listen to rumors in anvil & talk to gogron
spirits within: buy benirus manor from velwyn benirus in the counts arms in anvil.
some of the titles may be off i'm doing this from memory.
Fell free to add to the list everyone!
brother hood betrayed: bruma (i think you have to ask rumors, but i can't remember)
some fish one i can't remember the name: talk to a guy near the water, in a small town near the stables at imp city (gives you a ring that enchant's water breathing on self :):):):):))
I know that i know of some others but i can't remember them off the top of my head.
separated at birth: ask about rumors from folks in chorrel
Shadow over hackdirt: becomes available sometime after meeting Dar-ma in Chorrel.
The Forlorn watchman: Bravil rumor requires certain level i believe
MIssing paitner: talk to rythe lysandis' wife in chaydinhal ( i know the title is wrong but havn't done this one in a while.)
Zero Visibility: I started this off asking about rumors at teh old roxey inn northeast of where you exited the sewers.
___________ please forgive my type-o's I just got off work and am a little tired so its worse than normal, anyway i'm off to play some more before i crash :)
