No race changes or customization's of any kind.
No skills have been leveled up at all and no level ups available (no console commands used to set levels).
No spell tomes used or added.
Each quest has been completed "Organically" meaning that no console commands were used to set stages or add items to bypass stages.
3 files so far.
No.1: Completed main quest number 5 (The way of the voice) acquiring the shouts from the grey beards.
No.2: Started the Dawnguard quest line, at the Volkiar castle about to decide who to side with.
No.3: Sided with the Dawnguard. Only the Dawnguard quest line including all related side quests have been 100% completed.
All unique items have been collected including Saint Jiub's Opus, Arvaks skull, all the paragons and Auriels shield.
Note: if you wish to have Serana as your follower - she is at Fort Dawnguard.
I got tired of downloading hundreds of saves only to keep finding out they have either broken the quest line by using the console or are never actually "clean". Of course there is no better/cleaner option than starting a completely new character, however I personally have never encountered any issues with these saves even hundreds of mods later.
If you are wondering how I managed to "naturally" progress through the quest line without skipping quests or adding anything to my inventory...
It all starts with the tdetect command, disabling AI detection also stops any XP from being added to "sneak" and completely avoids confrontation.
tgm was used for unlimited sprint more than anything as I did not want to mess with the characters stats at all.
For instances where the kill command did not work (which was about 40% of the time) I spawned in some grey beards and turned on AI detection temporarily. This saved me from having to kill anyone.
tcl was used to speed up traveling and coc in some very rare cases.
(all have been enabled/disabled so you don't have to mess with the console)
I always found that messing with the quest line specifically causes many unwanted effects, while many are fixable - others take more time to fix than completing the quest naturally, and not to mention those tiny background issues that you only notice after hours into the play through when loading an older save (if you know which) becomes an unbearable thought.
If there are any popular requests, I may add those later on.
