From her hands, golden flames flowed into the makeshift barrier placed right before the closing Gate.
It barely covered it before the silver fireball arrived and exploded. All three of them turned blind and deaf by the explosion.
The only reason she had an idea about what was happening was because her hands still kept up the barrier.
The two flames met at the edge of two Realms, and a hard battle ensued. Sera used all her power keeping the barrier alive, while the silver flames hadn't lessened and, in fact, increased in power.
She felt the energy concentrate more as the Gate slowly closed in further, but it didn't make her job any easier.
The longer she held, the more her exhaustion increased. She felt small trickles of flame cut through her barrier and lick her skin.
