The more they talk about the master, more it seems that they are talking about Manohar xDDDD.
In some point, I think it's done intentionally to make us think that Manohar is somehow related to the master xD.
God this filler is trash, the story doesn't even naturally transition from Lith's adventures to this. It just switched to Manohar and Balkor out of the blue, and then it switched to this even more abruptly
