Ive played through many times. I don't care what people say, you have a mind flayer tadpole in your head. That's urgent.
So let me get this straight, if you had a tadpole in your head and people telling you your flesh will shed off, youd casually stroll about searching every little crack?
And the story tells you quite clearly that the tadpole in your head is not "normal", and there are several other "True Souls" that you encounter in the game that have had tadpoles in their heads for much longer than you, who have not succumbed to cremorphosis. So that should tell you that the sense of impending doom that is portrayed in the first few minutes of the game, is somewhat overblown.
Did you actually complete Omeluum's quest?
The motive behind the magic on the tadpole also creates anxiety and urgency. Unless you want to role play as an ignoramus.
