Exit out the back of the Oedon Chapel and immediately turn left to find Eileen the Crow, who warns you not to head to the Tomb of Oedon and offers up the Shh! gesture. Of course, this is the complete opposite of what you want to do. Return to Oedon Chapel and continue on foot, since the lamp is inactive, to Tomb of Oedon.
Tomb of Oedon
When you arrive you will find Eileen the Crow fighting Henryk and can choose to either aide her or let her die.
If you let her die you’ll gain her Crow Hunter Badge and her quest line will end, blocking off your ability to gain the Hunter Oath from the Hunter of Hunters covenant, but if you save her you will get the Approval gesture from her and the Heir Rune off the Henryk’s corpse.
Important: Sometimes this section will bug (possibly intended) and Eileen will not appear. If she hasn’t appeared you can die to reload the area and then return in the hopes she will appear… this is highly suggested as defeating Henryk without her present can result in breaking her quest line.
