Elixir of the myloc's focus and elixir of the myloc's strength formulas

Says Ghent (expert alchemist in Aughundell) starts the quest for these potions. I have them already but it's been a few years. My alt is in alchemy school, level 100.. ghent doesn't offer him the quests. anyone know what the prerequistes are for this quest line?

Or where the quest REALLY starts?
