well from the looks of things yea i'd say Wangnan and Karaka may or may not be brothers.and both sons of Zahard which further explains why Karaka is after Zahard

as for Zahards immortality, it's absolute it's not limited to the 134th floor, thats just where he and the 10 great warriors stopped climbing stopped. His immortality was limited to all natives of the tower. Meaning all the regulars who are found throughout the tower by headon and chosen to climb it. Meaning he can be on the thousandth floor and he'll still be immortal. The only thing rendering his immortality useless is Irregulars, because they are not natives of the tower therefore their not bound to the rules of the tower or administrators as we already know i.e. Bam, Urek, Enryu, Phantomimam however

Urek isnt concerned with Zahard

Bam is concerned with Zahard, thanks to FUG

Enryu is beyond over powered and being kept out of the story. he was merely a means to show just how deadly Irregulars can be as well

and phantomimam is just another examle of overpowered Irregularism
