Senior Researcher W.D. Gaster, Royal Scientist, personal research journal.

[REDACTED], 200X

I have secured the soul left behind by the royal child as Queen Toriel has asked.

I have repurposed one of the Core's conduits to house it indefinitely.

The more I observe the soul, the less Queen Toriel's demand to restructure the body seems feasible.

[REDACTED], 200X

The child's soul seems to contain a sort of databank.

I have begun deciphering the contents.

[REDACTED], 200X

The contents of the child's soul have turned out to be an encypted log of what seem to be events and sensations;

I believe I have found the child's memories.

The possibility of finding experiences of existing inside the child's body gives me hope for succeeding in my task.

[REDACTED], 200X

We have finished decrypting the SOUL's contents. My hypothesis was correct; these experiences give us something

to work with. I have unused blueprints for a mechanical body somewhere within the lab; construction will begin shortly.

Note: Junior researcher Alphys insists on refferring to the SOUL in capital letters.

[REDACTED], 200X

The mechanical body was a success.

The child has returned to the royal family.

A fitting way to turn the decade.

[REDACTED], 201X

The child has approached me with complaints about an 'all-encompassing numbness'.

The mechanical body must be ill-suited for supporting a human SOUL; I will begin work on improvements shortly.

My fears were proven, at least partially, wrong.

The exponential decay of mechanical life support has not manifested in bodies occupied by monster SOULs.

There is a sort of power source within human SOULs absent in monster SOULs.

It seems as if the SOUL is determined to reshape the mechanical body into its former one, breaking down life support in the process.

[REDACTED], 201X

The team has decided to name this power 'determination'.

[REDACTED], 201X

A remark from Researcher Alphys has given me an idea.

Perhaps a magical body would be more malleable?

I have instructed Junior Researcher Sans to acquire a dying monster.

I believe handing him such a significant task will help with his lack of motivation.

Junior Researcher Sans has finished mopping up the remnants.

The amorphous mass retained some level of cognitive capacity even after removing the SOUL, continuing to react

to stimuli despite losing its humanoid sihlouette.

I have decided to heed the protests of Researcher Alphys and delay questioning of the SOUL.

[REDACTED], 201X

From what I've gathered from the SOUL, it seems that the SOUL was overlaying its body image over the body's;

however without structural support.

We know for certain that a body already containing a monster SOUL is able to support a human SOUL; however,

the creature resulting from this union would prove itself too dangerous to consider the possibility.

Perhaps there is a way to override the monster SOUL?

The third iteration has passed away.

In addition, Researcher Alphys has quit her post.

This leaves the team consisting of myself and Researcher Sans.

Observation of the three subjects has revealed to me the way to subdue the SOUL by harnessing its determination.

Whether or not this will also subdue its consciousness will be determined soon.

I have readied the conduit and have purged all other copies of this journal.

If I do not succeed, Researcher Sans is to begin mass production of mechanical bodies for the SOUL to use on

a temporary basis, indefinitely.

[REDACTED], 201X

The procedure cannot be explained to its fullest extent

What can be explained through words is insuffeicient

I am executing it flawlessly

The SOUL is succesfully inside me

My visage is changing

Nonetheless

The SOUL is contained

I feel

Determined

[REDACTED], 205X

the soul protests inside me

everybody has begun speaking in tongues

my grip on reality has loosened

some kind of darkness is slipping between the cracks

[REDACTED], 26XX

it seems that my perception of time imprints itself on the actual time

the soul gnaws at me but i must persevere

[REDACTED], ????

there is only darkness around me now

photon readings negative

only core

only conduits

[REDACTED], ????

i can see the strands of time

concept of life is visible

[REDACTED], ????

our influence on reality is waning

i have looped a strand

flow not linear

not normal

repeats?

resets completely

[REDACTED], ????

I will call this the the

the ability to SAVE

[REDACTED], ????

determination taps into save

i have opened the gates

[REDACTED], ????

death looked at us

[REDACTED], ????

it takes all our determination

i am regaining control

my actions have manifested the ability to save

we float between time

[REDACTED], ????

somehow, i am able to reach my journal

it seems that some objects are connected to the metaphysical

we can see them

we can touch them

it was me who speaks in tongues

but my writing seems to be universally legible

[REDACTED], ????

sans

the soul has changed

it hears its name

it wishes to pass through the conduit

i feel death has touched it

[REDACTED], ????

i have broken the conduit in the lab

hide it from alphys

i am waning

i will throw myself into the core

i will break the conduits from within

the core's output will shrink

it should still function

[REDACTED], ????

the devil hears its name

it ripped itself from me

thankfully

it cannot see

unless

death looks at it

i will purge our time

i cannot return
