I accidently abandoned the quest named "A Relic Reborn (Omnilex)" after completing the chain up to Hydra.

When I speak to the quest giver, he starts the entire chain from the beginning. I have the Unfinished Omnilex in my Inventory. Can you please reinstate the quest up to the Hydra fight?

I do not wish to repurchase the base materials and run through the quest parts I have already completed.
