How to Find Count Ymir and Complete his Quest

First Meeting - Cathedral of Manus Metyr: Travel to the Cathedral of Manus Metyr in Scadu Altus. This requires completing Castle Ensis first. Navigate through Scadu Altus, find the large hole south of Moorth Ruins, and carefully drop down. Follow the ruins, dealing with Horned Shamans, to find the Golden Arcs Incantation. Continue through the dilapidated building, drop down to the floor, and enter the cave in the southeast corner. Follow the cave to a ladder leading to Bonny Village. From Bonny Village, travel east, crossing two rope bridges, until you reach the "Bridge Leading to the Village" site of Grace. Continue north to the "Church District Highroad" site of Grace, then follow the path south to the Cathedral of Manus Metyr. Inside, speak with Count Ymir, exhaust his dialogue to receive the first Ruins Map and Hole-Laden Necklace. Reload the area to find Swordhand of Night, Jolán. Speak with her, then return to Ymir.

First Bell - Finger Ruins of Rhia: Access this area from the Cerulean Coast, south of Gravesite Plain. Travel through Ellac River from the Castle Front site of Grace. Head south past the Ghostflame Dragon, collect the map fragment, and reach the Cerulean Coast Cross site of Grace. Follow the ledges northeast down to the coast, continue northeast, and go over shallow water. Head north over a large stone coffin to find the Finger Ruins of Rhia. Locate the circle of stone fingers in the northern center of the area. Approach the finger hanging in the center and choose to "Sound hanging bell" using the Hole-Laden Necklace. This rewards you with the Crimson Seed Talisman +1.
