From what I have gathered, your lightning elementals are refered to as Tempi. They are from the broken lands, which is accessed through a portal located in Valdanis City. These Tempi have been at war with the locals of the Broken Lands for a long long time, so your foe is war tested. Two factions of the Broken Lands have been fighting the Tempi, the Paladins and the Crusaders/Barbarians. Their have been at least four documented campaigns against the Tempi. While they may have been victorious in pushing the Tempi back, they lacked a way to finish it.
The Paladins are the bigger force. The were basically knights that were sealed in the broken lands with the old families. They live by the code of conduct, but that code may have changed slightly from the more commonly known ones. They are against magic, as Tempi were technically summoned. I believe Syver made contact with them. He is likely to know more.
The Crusaders or Barbarians are another force. We just recently helped them recover an artifact to help in their cause against the Tempi, so they might be more likely to provide aid in any said assault. They use celestial magics, which is different, but focus strictly on the element stone. They are also able to self beserk and swing really hard for a limited time when they do. Again Syver is likely to know more about these guys.
The Tempi are ruled by a Djinn, though not like a typical Djinn. A tower of magi were sieged in their tower and banded together to summon this Djinn. I *think* requested a wish from the Djinn, and likely poorly worded that Djinn twisted destroying towns and mass death and destruction. The Tempi is simply the army. Should note as well the Tempi can create portals of any place that has been rifted to or from, so rifting is ill advised. Their are Rift Paladins whom can sealed these or prevent rift locations from being accessed from the Tempi.
Also the locales in the Broken Lands have Ward Stones, that seem to to keep the Tempi away, though they did recently manage to destroy a town that did have a Ward Stone and attempted to merge Arden and the Broken Lands using said Ward Stone I believe.
Hope this information is useful to dealing with this foe.

P.S. I don't know if Drevic portals will cause tears like rifts, I would think it would be likely.
