yes- from the way i'm reading that: you defeated Asmadius, got Lovis's Soulstone and the book, and then met Damian. you're not quite that close to getting to the battle tower, but you're nearly there!

You now have to go on to Sentinel Island, and begin the process to reclaim the battle tower from Laiken.

if you agreed to free Lovis, return to his tower and give him his soulstone.
