The shattering ice was the challenge that Walker encountered over and over. For whatever reason, he was losing the balance. But it could all be added up to the division in his attention. Having to walk through the air to keep his pace and also to maintain the balance between two different elemental mana that would prefer to be separate was taking its toll.
However, he would not be giving up. He knew that the more things he could do the better. The more fusions of mana that came naturally to him would be more means to defend those he cared for when he was in danger.
This desire only grew the more he forced the two elemental manas together. The falling black ice crystals were like a shadowy snow falling around the ships. Unknown to Walker, many of those on watch had noticed this and were wondering what was going on.
