Senic was also a Scion of Surabar, descendant of the man who discovered Cauldera, helped settle the region and aided in the defeat of an ancient demonic army.
Senic excelled at overcoming even the most daunting perils, striking where it was least expected, and taking advantage of enemy vulnerabilities. Fleet of foot and skilled in combat, he could navigate any battlefield with ease, aiding allies wherever he was needed most.
Colleague and friendly rival of Midnight since childhood, Senic ran into the Keepers on their search for the orphans while searching for his sister Jasmin who had also been abducted. He helped recover the missing children, ended the goblin menace, helped find the missing Wands of Control Water to save the city during Flood Season.
Senic Halmar was slain by Kuo-Toa during rescue of Zenith Splintershield.
