What is the name of the song playing at 01:15 of Magi, ep 25?
Well after going through a whole lot of songs in a playlist on YouTube, I finally found it. The song is called "Warrior Ships" here.

Sadly, I could not find any information on the song that I could add to this answer such as who composed it or wrote it.

PS: I am not sure whether it is "20 Warrior Ships" or just "Warrior Ships". I had no idea, to be perfectly honest, but this is definitely it.
