The Terra Titan

When the Terra Titan stood up behind the walls of Kalusia that were visible not too far from the empress' army, she quickly commanded them to scatter, as staying close to each other gave the titan a better shot at eliminating several soldiers with one attack.

My companions and I took flight, but before I could rush to the giant, I was stopped by Gina.

The Terra Titan was one of the protectors of Kalusia, and Gina told me that due to his mission given by Garon, the God of Beasts, he couldn't use his titanic powers for anything other than protecting the nation.

'Makes sense, or Zagor could have just simply sent him to destroy their enemies' cities and armies…' I thought.

Gina expressed the importance of not killing the titan, and I somewhat agreed with her. 

I mean, he was obviously being controlled by the devil, but he was also extremely dangerous, and not taking him out could cost the lives of dozens, if not hundreds, of soldiers.
