Tyler only watched the fortress and everything around it vanish for a moment as he immediately teleported back to the castle in an instant. He had let his anger get the best of him and had consumed all his mana with the last few skills he used.
Warp creation was the highest level skill in his Spatial skill series and as such, consumed an absurd amount of mana. In the end, he had forced himself to use it twice despite his current state, and thus he was beginning to feel the side effects as his vision went white the moment he and Liz appeared in the main hall of the castle with the last of his strength.
He felt a wave of exhaustion wash over him and immediately lost consciousness but his fall was caught by Zelda who had instinctively sensed their arrival and moved to greet him. Her shadowy figure rushing towards him was the last thing he saw before he passed out.
'Yes... That's it. Just a little more. It won't be long now.'
