Mephistopheles had indeed discovered it.
Though this guy was famously arrogant, it didn't mean he wasn't intelligent.
Besides, since he dared to covet the Weave, he naturally had to be wary of Mystra and her allies.
But Mephistopheles bent down and looked at this God of Singing, how long had this guy who seemed like a mere bard been in his dominion?
Even the elves were willing to join Miliel and come forth to battle; it surely wasn't for a short time!
Why had he never noticed?
He was almost furious, "Miliel! When did you come to this world? Damn it! You really would go through hell and high water for that bitch Mystra!
Aren't you a True God yourself? Are you so used to living a life of hiding and secrecy?
Lucky bastard! If I had discovered you earlier! I would have flayed and dismembered you by now!
The drums made from your skin would sound so delightful!"
Miliel said nothing; he had no intention of stopping his singing to reply.
