Completely stuck

I'm in a bit of a bind because I have a handful of quests left which either require me to go to the underworld which I can not get the ferryman to take me to even though I have a golden bow or interaction with the grey horror which I vaguely recall seeing before but I can't get him to appear at night in the cometary.
I'd really appreciate some help as I've been stuck for ages. Thank you

Please see if you can get help for those quests at my website---www.catacomber.com---there should be some similar questions there if you search.
