The evil path is too hard to find. It is easy to get into conflict with the goblins without finding the option to ally with them.
The whole absolute path seem disjointed and could do with a few encounters pointing the player towards it.
There is a lack of reward for the player in siding with the goblins. The followers of the absolute should explain why the players group should learn to control the tadpole instead of getting rid of it. The True-Souls being unaware of their tadpoles makes little sense considering what happened after the death of Edowin. Something similar is likely to have been noticed by them earlier

I sometimes use thought experiments. I don't necessarily believe in every idea I post for discussion on this forum
