Like Suboxide said, plenty in the Lore to allow for a Marauder-only Spell.
New technology really should make possible new weapons systems. This is different from having a characteristic spell (fire, poison, shockwave, electricity), as all players have greater or lesser resistances to these, depending on their race and there would be no corresponding resistance to any new Marauder weapon.
Marauders are not a race, however, so it would be a Faction thing and technology could easily play the part.
If not technology then perhaps a Marauder-only offensive magic spell based on Matoxia or Goo. If they have the ability to throw Matoxia or Goo around that would be plausible. There would, however, be no racial resistance to this so it would have to be balanced out somehow.

The Marauders are shrouded in mystery and it is often said that they possess strange technology that has never been seen in the New Lands. Certainly, the armour worn by some of the Marauder leaders was not known in the New Lands until they brought it there. More recently they've also been shown to have access to perfect crafting materials that are completely without flaw.
The Marauders also have shown to have superior encrypting technologies and the ability to teleport without aid from the Kami or Karavan.
It is believed that a mysterious substance referred to as matoxia is somehow tied to Marauder technology. The Marauders also seem to have no qualms about using Goo in their weaponry.
