First up you'll want to check the village of the albinaurics in southwest liurnia, where albus is hiding in a large pot near a perfumer - roll into it or give it a solid hit. The critical timing here is getting his medallion half before heading to castle sol, since collecting both pieces too early ruins the whole questline. After grabbing the right half, make your way to lakeside crystal cave and take down the bloodhound knight - watch for his quick dash attacks, he'll flash blue briefly before lunging so dodge right as the glow peaks.

Once you're outside the cave, you'll spot latenna at slumbering wolf's shack with her wolf lobo - show her the medallion right away to gain her as a spirit ash summon. She's positioned by the shack's entrance and won't move until you interact with her. The next major phase triggers after reaching mountaintop of the giants, where commander niall guards the left medallion half in castle sol. During his fight, keep distance when he buffs his knights, and wait for his prosthetic leg slam which leaves a brief opening for damage.

With both medallion pieces, head to the grand lift of rold and use "hoist secret medallion" to access the consecrated snowfield. Your final objective is the apostate derelict in the northwest - you'll recognize it by the massive albinauric woman. Summon latenna near her for your ancient dragon smithing stone reward, but remember positioning is key since latenna needs to be placed within interaction range of the giant woman.
