The Bridge: In Queynos there is a guy named Hansl Bigroon. If you talk to him
he
will talk about making a bridge to Odus. He needs a list of engineers
delivered to Antonius
Bayles' messenger. He refused to give me the list to someone who conned
indifferent, so I
don't know if a friendlier face will get it. I have been told that if you
keep asking him about
the engineers (the text is not bracketed) he will drop the note, which lists
the names of the
three engineers. The human engineer is located in the arcane science building
in Freeport,
but I don't know what you need to do to get him to respond (giving him the
note doesn't work).
But if you talk to Rucio Divella in the office of the people he says that
Hansl Bigroon is the
office manager. If asked who are the other engineers he says he saw them
once, one human,
one dwarf and one gnome. The gnome he said was followed around by some sort
of automation
(perhaps the one in Steamfont?). I am not sure where to go from there, but it
sounds
intriguing.
