You are Egrassel, son of Tadmavriel. The Spark hasn't been created yet, and you only suspect what your Father is doing.

Tadmavriel was standing in the middle of his lab, arms folded, looking at you with obvious displeasure. His ears twitched slightly in annoyance. You came here to find out what he does day and night in the lab, without letting anyone in. Tadmavriel was maddened by your concern. Not that you're worried about him, but that you're so annoying about showing it. There was a desire to simply kick you out of the lab, but Tadmavriel held back that urge.

— You don't dare judge me, son, — Tadmavriel said in an almost hissing voice, lifting his chin slightly and looking down at you, — it's none of your business what I do here. He turned around, hands clasped behind his back as he turned to you ,and walked to the window, not wanting to see you. He was trying to make it clear that the conversation was over.
