This one has been in the workshop for quite a bit, glad to see it's being out in the limelight like this. (And yes this the only image I could find which accurately describes the situation.)

Creator notes:
"when you long elevator" - THi

070 - Short Elevator

Another original-ish track for when Monster Kid emotionally lashes out and tries to run away from Frisk and Flowey. Which leads to a little heart to heart ;)

Days to Christmas Countdown: 11

HEEEEEEEERE's the full (first) 100 follower special as promised, plus the 2nd "12 Days to Christmas" song! Sorry it took so long for this song to come out, but I was incredibly busy with finals and trying to make this song as good as I possibly could.

The main cover starts at 1:02, before I finalized everything I decided to make an accompanying Taletwist "BtERtD", hence "Defiance of Fate". I hope you enjoy this track!

[12 Days to Christmas - Taletwist] Defiance of Fate + The Rogue Strikes Back (Cover/My Take)

We all once were happy friends/family. Then we decided to build our own server away from everyone else, which caused conflict between the Outsiders and SMP members. Headdzo won the war and we made our server. As soon as we made the server things were fine, but started to go downhill, causing our separation.  Soon we realized that the server wasn't helping us in anyway and we wanted to delete it, but we needed 8 Outsider Souls to do so, causing us to have to wait years and years for our freedom.
