Can anyone help me find a fanfiction I read years ago revolving around Spike and Twilight?

[Taychrexis 0]

The fanfiction had it revolving around Spike and Twilight.

Spike would sleep,  and Twilight would be waiting for him when he woke up.

Some key points:

Equestria turned into a democracy.

There was a war between the dragons and ponies.

Spike woke up in the last part and Twilight was dead in his cave,  and he like screamed and recreated the universe or something.

Please freaking help me.
