The Elderseal

The Elderseal
The Elderseal is a mysterious marking bound to one of the hands of the equally mysterious child, Balmos. This mark seems permanently bound to his hand and any attempts to remove it have been met with a nigh-instantaneous freezing process that would freeze the hands or tools of anything coming in contact with it.

As explained by the scarf accompanying Balmos, which was revealed to actually be a sentient familiar thought to be summoned by the boy at some point in his life, this "Elderseal" acts as a power seal to keep the boy's full power locked away until he is able to fully control it.

The appearance of the seal also seems eerily similar to the seals of the Asura and indra reincarnations though does not seem to possess the same power as those two.
