Certainly one of the major contributors in the current BatWorld, Melemkor's work spans throughout the game; implementation and maintenance of the new sailor guilds and ships in general being just one part of his repertoire. Besides those, he is also the mastermind behind shipquests, though some of the work was delegated to other wizards (Malack, Hablo, etc.)
Last, but certainly not least, we should mention his involvement with the great continent tune, which moved us into the Age of Exiles. Melemkor was the major architect behind this major change, although many other wizards also worked on the new content.
Melemkor speaks: "Thanks for playing :) Some of my projects have been really popular, others have had decidedly mixed opinions; I hope things have generally worked out well, but it's always keeping things exciting for the players that keeps me coding.".
