I like the way Merm's threads are titled, so I thought I'd copy it.

In the Maelstrom version of the quest "It Kills With Fire", one section of the journal states this:

"Winning the battle with a party of four fully enlisted members of the Maelstrom will earn you greater rewards."

Later in the journal, it says:

"Winning the battle with a party of four fully enlisted members of the Order of the Twin Adder will earn you greater rewards."
