Hi, DBG here!

I can’t remember where this track popped up, so I’ll look into it later.

Named in Island Mode: BGM 5

Lord of Dice - Battle Track

Lord of Dice - End of Time (off vocal + chimes)

I have google translate lyrics from a friend, don’t mind the inconsistencies that are present.

To find the fragments of the trapped memories

It rises to the end of the stopped time.

I go towards my small wish to bring

back my one and only precious memory. 

(Repeat)
