Thelas' pillows is good example. There are no journal entries for this quest, thus it does not have a proper quest ID.
"Drarayne's Pillows
This is one of the more obscure quests in the game which takes a bit of luck, and a good memory to discover. On a Fighters Guild quest to kill some rats in the house of Drarayne Thelas, you may have noticed the unusually large number of pillows she keeps.
Pillow Shipment
On the other end of the island, far to the north in the Sheogorad Region, you'll find an Abandoned Shipwreck, north of the Sanctus Shrine (far west of Dagon Fel and just north of the Vas stronghold). Inside the cabin you'll find an invoice for 40 pillows addressed to Thelas.
While you cannot deliver the pillows, you can give Thelas the invoice and receive an "Extra-Comfy Pillow" as a reward (talk to her about a 'Pillow Shipment' when you have the invoice). The pillow merely changes the message you receive when you wake from sleep to "Your sleep is very restful on your Extra-Comfy Pillow"."
It takes a great immersion to the game and it could be hard or easy as you want, because you don't have feeling that you didn't end sth.
So for example for Dragonbone cuirass it could be way:
1. You heard in some bar (maybe some dialogue between NPC's). That ship recently crushed after storm somewhere on coast (they say some details)
2. In the ship you find captain notebook in which you read that they were treasure hunters.
3. Treasure map is hidden somewhere on the board. You have details how to find it in notebook.
4. You find map and go to mudan grotto for cruirass.
There could be several quests like two before. The cool thing is that this is quite easy to implement.
