Adrian looks to Wren and says; "I am fine to be indebted to Waterdeep watch and thus compelled to finish this task. We need Sherezza's abilities locate the necromancer and her horde so we can finish the task after all. Already allowed to copy freely scrying spell is well worth of my investment as I can make easily money by preparing scrying spell and scry for people who lack it. Or rent my spellbook and let them copy spell from me."
