I have been itching to make a world timeline instead of a local timeline because normally Localized Timelines tend to ignore butterflies in other areas and lack liberties, I am reviving this timeline because I am interested again in this POD, this is a world timeline - not a localized timeline..
MAGELLAN IN EDO

The first known contact between Guam and Western Europe occurred when Ferdinand Magellan, a Portuguese explorer, anchored his small 3-ship fleet in Umatac Bay on March 6, 1521. Magellan had started out in Spain with five ships but by the time they reached the Marianas they were down to three ships and lost close to half their crew. One of the five original ships got destroyed, and after seeing the first ship go down another ship had a mutiny and took off. So two of the five ships and its men were lost by the time they got to the Marianas. Hungry and weakened from their long voyage, the crew quickly prepared to go ashore and restore provisions. However, the excited native Chamorros, who did not share the Spaniards concept of ownership or subsistence living, canoed out first and began helping themselves to everything that was not nailed down to the ship. "The aboriginals were willing to engage in barter... The natives exchanged their fruits for weapons and guided them in their islands.
Details of Magellan's visit, and the first known Western documentation of Guam and the Chamorro, come from the journal of Antonio Pigafetta, one of Magellan's 18 original crew members to survive Ferdinand Magellan's circumnavigation of the globe.
The Chamorros were kind and accommodating to Magellan that some converted to Christianity, although some were against the white explorers the nobles were kind to Magellan’s expedition since they saw him in good faith.
Magellan decided to discover the islands north which was also settled by the Chamorro since he felt that the Chamorros were a nice people and want to discover more about them. He discovered new islands at the north of the island of the Chamorros called the Marianas Islands and then islands which were uninhabited (in OTL which is now known as Ogasawara/Bonnin islands) which were empty, which led to the Izu Islands which contain Hachijo Jima and Oshima and later to Edo in Nihon where they were able to tour and they toured as well to the Southern Islands.
On their way they discovered a big island , south of Japan and the Kingdom of the Ryukyu filled with Savages, he called his settlement in the island, Nueva Valencia(OTL Taiwan).
The crew of Magellan visited South of China particularly Canton after leaving Nueva Valencia, then they arrived in Tonkin Gulf then to Borneo where they set sail to the Indian Ocean and passed to the Cape of Good Hope then Circumnavigated Africa and were able to arrive back in Spain on October 1522 and Magellan said he arrived safe and went to see his son and wife again and report to King Charles V in order to report his journey and about what he found out, this time, Charles V is still celebrating his own victory against the comuneros.
