This is the Soundtrack used in Punishing Gray Raven's Frozen Darkness event and Rosetta Boss theme, made ny Haloweak.

Stealth Track is not from the original Narwhal Track but instead it's the Dorm Track (cause it was a big pain to find a good portion to loop for Stealth in Narwhal so I chose the Dorm track instead and I plan to use it on future PGR OST mods)
