I was always very intrigued by these unsolved quests of vanilla EQ. Especially the ones revolving around the mysterious Unkempt Druids and their strife with the Surefall druids. Jale Phlintoes in South Karana remains one of the most interesting NPCs in original EQ.
I have always suspected these two quests being somehow linked:
The Nitrates and the Assassin and
The Unkempt Druids. A possible third connection could be this one:
Solvedi Scimitar because it is directly related to the Unkempt Druids, and the quest reward is slightly inferior to the turn in quest items...
I think someone originally planned for druids to have the option of choosing sides with the Unkempt at the expense of Surefall Glades faction. With possible rewards in store...
