Let's get started with some quest concepts. All are subject to feedback and modification
Beginner quests:
1. A journeyman with the Mages Guild wishes to exchange notes regarding magical items found within the current region. Take some of the Archaeologists' notes and receive the mage's, and return for a simple reward of between 50 and 125 gold.
2. A valuable book of notes has been left in a regional shop, as the owner was too busy to wait for you. Retrieve it and bring it back to the guild for a simple reward.
3. The potionmaker requires a bag of ingredients from a shop in another city. Bring it to the guild for a simple reward.
Novice quests:
1. The guild has been pointed toward a record regarding the regional ruler's ancestry. Go down into a dungeon, find it, and bring it back for a reward.
2. A local expert wishes to find an object of historical value in a dungeon. He/she will accompany you into the dungeon, and depart once it is found.
Intermediate quests:
1. An expert in the guild has disappeared entirely, with only vague rumors as to his/her whereabouts. Speak to townspeople, follow rumors, and try to find the expert, who will be holed up in a residence in a city.
2. A politically sensitive document has been taken from the Archaeologists' possession. Find the thieves and take it back.
Advanced quests:
1. Carry an object of significant value to a regional expert in a dungeon. Enemies will seek you to steal it off your corpse.
2. Lich interrogation quest.
Endgame quests:
1. An artifact is rumored to be held by a local noble, who refuses to part with it except for an exorbitant sum or a particularly egregious and illegal favor. Follow his/her instructions or receive help from secret associates to blackmail/slay the noble to obtain the artifact. Return it to the guild for a large gold reward, or keep it for yourself at no reputation loss. (Long and difficult)
2. An artifact has been unearthed deep within a regional dungeon, but all who touch it have suffered a curse of death. Find the cause with the help of associates, or face the serious consequences of taking it early. (Perhaps daedric cause, requiring some form of exorcism?) (66% chance of an ordinary object, 33% chance of a real artifact.)
