https://vanillawowdb.com/?object=1557 Lillith's Dinner Table can be found in Gunther's Retreat on the Brightwater Lake in https://vanillawowdb.com/?zone=85 Tirisfal Glades. [66.7, 45]

It is used in the quest [10] https://vanillawowdb.com/?quest=410 The Dormant Shade - the quests description describes the table as an ""old, beaten, bloody table"". The quest must be somehow broken, as it doesn't award you with anything. not a single copper, not to mention silver or gold, not even experience points - even reputation isn't given by this weird quest.

There isn't a known follow-up or a prerequisite quest in order to complete this one - its absolutely good for nothing - even the quests description says nothing. Does not count towards the loremaster-achievement either.
