The Elder Scrolls V: Skyrim Special Edition

INTRODUCTION
There are many side quests available in Skyrim, however identifying them may be difficult. Side Quests do not include any tasks listed under the Miscellaneous heading, but are named quests that don't associate with any of the other questlines (Main Quests, Faction Quests, Daedric, Civil War, etc...)

Generally side quests will have a unique name and will be surrounded by the following decoration in the Journal.



SIDE QUESTS
Since the amount of side quests available far exceeds just 10, I will list all the quests known to count for the achievement, as well as listing the order in which I completed my first ten.

Remember you can choose any 10 to complete, and seek them out at any time, personally I finished quite a few sidequests before even reaching High Hrothgar (for the Main Questline).

EASY SIDEQUESTS
Of course the sidequests you complete can, and probably will, be different to mine this is just a loose guideline of some of the easier sidequests. Use this if you are late into the game and still haven't encountered ten sidequests.

The Forsworn Conspiracy - Witness Weylin's attack against Margret upon entering Markarth.

No One Escapes Cidhna Mine - This quest will begin automatically upon completing The Forsworn Conspiracy.

Blood on the Ice - Visit Windhelm at night and you may hear some citizens speaking about a murder. Speak to the Guard in the Cemetery to begin the quest.

The Golden Claw - Enter the Riverwood Trader (In Riverwood) and ask Lucan about the missing item. (Note: This quest should be completed alongside the Main Quest "Bleak Falls Barrow".

Laid to Rest - This quest can be started in Morthal by speaking with the Moorside Inn innkeeper, Jonna, who will mention the burned down house nearby.

Rising at Dawn - Speak to Falion in Morthal if you ever become a Vampire.

The Man Who Cried Wolf - Speak to Falk Firebeard in Solitude (usually found in the Blue Palace).

The Wolf Queen Awakened - After completing the previous quest for Falk Firebeard, this quest will start. (You must be over level 10.)

The White Phial - Speak to Nurelion, found at The White Phial in Windhelm.

Ancestral Worship - Talk to Golldir at the entrance to Hillgrund's Tomb.

According to the official guide there are 23 side quests. Which I will name and give the prerequisites for here. However there are others not in the guide that people have found, you can find these at the bottom of the list or in the comments.

However the symbol that looks like a simple "knife" shape (the symbols to the left and right of the quest name) could also mark the sidequests. Click the link below to check the symbol.
