Undertale timeline theory: The year Chara came to the Underground,
is the same year the royal family moved the capital from “Home” to “New Home.”
Here is my reasoning:
At Toriel’s house in the Ruins we find a calendar from
beginning of the year 201X and we find a calendar from the end of the year 201X
(with the day of Chara’s arrival circled on it) at Asgore’s home.
When Toriel left her husband a year probably already passed (at
least) before Chara and Asriel’s death and I doubt she would have taken
something like an old calendar with her during her sudden disappearance. (She
was also allegedly transporting Chara’s body to the Ruins to be buried so it’s
most likely she couldn’t take much else with her)
My guess is that during the move from Home to New Home the royal family left
most of the houses furnishings behind in case they ever needed to come back to
the old capital for business or vacationing.
Also, building a new Capital
City would take time, “Rome was not built in a
day,” after all. But one of the first buildings to go up would have been the
Royal Family’s living quarters, and considering how humbly they live compared
to other examples of royalty, it would have taken roughly around a year to complete.
There are also the living arraignments of Home and New Home
to consider. The kid’s room in Home has one bed and the table setting in the
living room has two adult chairs and one kid’s sized chair. Whereas in New home
we see two beds in the children’s room and a total of four chairs.
This would mean that Asriel had lived in Home for a while, which is much closer
to the Ruins where Chara fell in, making their chance meeting more probable
than if Asriel had been living at New Home during the year 201X.
Another plausible support for this is how the monster
history book stated that the monsters went further into the mountain because “They
feared the humans no longer.”
Could Chara’s coming to the underground and
becoming a part of the royal family contributed to this change in sentiment?
