This quest is called 'City Beneath the Sea',
for Adventurers levels 180 to 220.
Lord Vashir [The Towne of New Rigel] is the master in charge of this quest.
Recently, intelligence has seeped through to me indicating that the
fabled city beneath the sea may in fact exist. What's more, it may be that
Lord Vendredi is concealing it from us. Should this city exist, we must
find it and make contact with the thieves guild for surely they could impart
some knowledge to our own guilds. It is up to you to journey to Sigil, find
out what you can about this city, then locate it, before meeting the chief
of the Atlantis thieves guild. Talk with the Sigil guild leader and hear
what he has to say about this city. May the powers guide you!
Upon successful completion of this quest you can receive:
