Aelaer

I just followed this and was only given the perform ritual or counter ritual. Edit: played again and this time I got all the occult artifacts, and drove Irene over the edge, in addition to the above options. Then I got the option for this ending.

This game is not fun, to anyone considering buying this, be warned. The story is not engaging. The combat is a slog. And poison will do 20+% damage to you every turn, and the enemies in the beginning of the game love to spam it. You also get multiple actions per turn, but your last action will need to be defend to avoid INSANE damage, even when wearing the best armor available...

I would also be interested in joining a guild of trophy hunters for this purpose.
