List of significant canon changes

The World Wanderer idea is a fanfiction/crossover and thus includes many changes of events or even characters of the original canon. Here is a full list with short descriptions of all the significant canon changes that were made during the creation of this personal fanon.

Oberyn Martell, Din Djarin and Javier Peña
To solve the problem of Pedro Pascal playing three very different characters, Oberyn Martell (Game of Thrones) and Din Djarin (The Mandalorian) were combined to the new character Oberyn Nymeros Din Djarin Martell, a dornish prince that was sent to Mandalore as an experiment of the SLSS. Javier Peña is Oberyn's alias when he goes to one of the Earth Galaxies and joins the DEA in its fight against Pablo Escobar.

Billy Russo
Billy Russo (Marvel Cinematic Universe) is not of mankind and son of Carla Russo in this fanfiction, but actually of yeolandorian origin and an experiment of SLSS gone wrong. He suffered from Hazing Death for many years and returns to Yadvandor after the. That way the Russo storyline of Season 2 of The Punisher does not happen.

Bellamy and Octavia Blake
The world of The 100 does not exist as such in this crossover and thus the Blake siblings aren't used in their original form either. However, there are characters that carry those names in the Paranormal subplot that are  highly  inspired by the The 100 characters, which is why it needs to be noted here.

Tolkien Universe

 * Battle of the Five Armies: Kili and Fili do not die, as Azog doesn't go after Fili himself but sends Bolg to kill the both of them. After Kili sees Fili's wounded and unconscious body dropped by Bolg he attacks the latter in order to protect his brother from a fatal strike, which results in the fight between the orc, Kili and Tauriel. In this version, however, Bolg is not victorious over Kili and can be distracted by Legolas before either of his previous opponents are killed. Fili does later recover from his wounds and is crowned King under the Mountain as he is the next in line of succession. Meanwhile Thorin, although later resurrected in this fanfiction, does die the same way as in the movie, impaled by Azog shortly before taking the orc down with him. Azog, having faith in his offspring having succeeded in the mission of killing the brothers, does still die in conviction of having wiped out Durin's line.

Game of Thrones

 * Daenerys' fate: Her doings stay the same in this version until the destruction of King's Landing. After she snaps and the Targaryen Madness takes control over her, making her brutally burning part of the capital and its inhabitants, she breaks down in shock and horror over what she's done. Jon Snow waits until he sees the dragon flying alone in the sky, before he storms the throne room with a handful of northern soldiers. He finds Daenerys on the floor, shaking and cradling meters away from the throne. When he confronts her, telling her that she can not reign over the Seven Kingdoms after what she's done, she reacts with disbelief and anger. Even though she already admitted her fault to herself she can't understand why the love of her life could take her greatest dream from her. Aware that he could not overpower her if it came to battle, Jon hesitantly decides to use the moment and have her locked up until a solution is found.
