Sevarian had not expected the leap made by Serphia as the Night Elven Captain suddenly landed mere feet away from them. 

"Curse me!" The shadow mage exclaimed as he stumbled backwards while Serphia advanced upon the two men. Sevarian stepped next to his apprentice, before quickly pushing the acolyte in front of him to use as a human shield. The apprentice did not have much time to realize what his master had done before Serphia's sword had already entered his torso in yet another precision strike from the Night Elf, and blood was gushing out from the wound.

Using the precious few seconds he had bought by sacrificing his assistant, Sevarian fumbled with his staff to aim it at Serphia.
A dark, purple lightning shot out from the shaft of the staff and flew into Serphia's shield, where it caved in a small part of the shield, creating a small bulge. The painting and outer layer of metal where it hit began to wither and erode, falling off the shield like leaves in the wind.

"Die you cursed elf, die! DIE!" Sevarian roared out as the shadow mage continued to cast dark lightning after dark lightning at Serphia; all of whom were blocked by the sentinel's large shield. Although he succeeded in pushing her a little back, the Captain was suddenly able to step forward and slash down with her sword, cutting his staff in half.

Realizing what had just happened; Sevarian immediately dropped the remaining half of his staff to dig his hand into his robes. As he stepped back, he pulled out a silver lined flintlock pistol. 
Moving it up in a frantic motion to fire it, Sevarian spared not a moment to try to aim as he snapped off a lead ball at Serphia. Before the agile Night Elven warrior could retreat behind her shield, the bullet had already hit her in the lower right part of her ribcage, just beneath her armor where it entered her body.

Reaching his left hand into his robe, Sevarian pulled out a black wood wand; promptly snapping off a shadow bolt that sent the stunned Captain's shield flying away. 

"Know pain!" Sevarian hissed before summoning a wave of dark energies that he threw straight into Serphia, throwing her off the balcony and down into the room. For the Captain, as she was hit by the dark sorcery; it could feel as if all her strength was taken for her for a moment, replaced only by a dooming chill and feeling of emptiness, almost as the spell was tugging at her very soul.

Sevarian stepped back from the edge.
Not risking a moment to observe where the Captain had landed, the dark mage turned around and ran down the opposite end of the corridor away from the balcony; and not throwing his fallen student as much as a glance before he disappeared down into the tunnels below.
