Zimberfizz

Zimberfizz is the imp minion of Nomad. He is found in the Soul Wars lobby and appears during the tutorial. He's also the starting point for the Grandmaster Quest, Nomad's Requiem. You can exchange Zeal points with Zimberfizz.

The player must kill him twice in the Soul Wars tutorial and he will hit very fast zeros on the player, he has 100 Life Points. He will drop one soul fragment when killed. He is then teleported back into existence by Nomad.

During the tutorial, after the player has been killed by Nomad, they can return to the soul obelisk and have a conversation with Zimberfizz. It is revealed that Nomad has a high Hunter level (at least 71) as he had caught Zimberfizz via magic box. Nomad also actually built the soul obelisk, as Zimberfizz states that he had to carry the materials to the site. It is also revealed that Nomad "certainly knows his way around slayer monsters, too".

After Nomad's Requiem, Zimberfizz acts as a replacement for Nomad, as well as adopting a new appearance, with a Top hat.

Postbag from the Hedge
In the Chaos Elemental's 13th letter, in Postbag from the Hedge 41, there is a paper which has "Hardens South" written on it. That is an anagram for "Use Shorthand" and the text appears to be written in Teeline Shorthand. The translation is "Uv b wd abt Sl Ws. Nmd is tb frd." Transcribed it says, "You've been warned about Soul Wars. Nomad is to be feared." This makes sense since in the included postbag, we are told that Nomad knows where the souls go and Zimberfizz says "I can see it on his mug." Along with the other clues, it seems that Nomad could be eating the souls or storing them for his evil scheme. The cryptic note in the suitcase confirms this.
