Mace (Balthazar) + Silas = Balas

Ship Name
It is incredibly critical that it is Balthazar and Silas because that is when they truly clicked. While Mace loved Silas because Silas was comfort, safety, and new exciting things. Silas loved Balthazar for his companionship and how he adored and would stand up to Silas. I think.

Also, "balas" is spanish for BULLETS so like, it's perfect.

History
About 150 years ago, Balthazar was told by his "boss," Finn, to go and entrance a man and that he would know who it was. Of course, Finn was right and they were introduced.

Over the next few months, their relationship progressed until Silas found Mace on the steps of Finn's "house." Silas brought Mace back to what we can only assume is his house to heal. They bonded a lot until Mace brought up the fact that Finn had every intention of coercing Balthazar into killing Silas. Silas began to truly love and trust Mace when he denied the opportunity to plunge a knife into his chest.

Unbeknownst to Silas, Finn brought Mace some...persuasion. Soon after, Silas passed and Lux turned Mace into a Soul Eater.
