The first time Kaiju spotted the burg was when he arrived at the Trial, floating above the canopy of the gigantic crown of trees. Afterwards, he had never spotted it due to the darkness, as even the sunlight in the Hellish Trial could not be compared to the sun.
Kaiju received the information from them about the direction of the burg, and now, he was nearing it. At the same time, he was baffled by the absence of the Thralls, even now that he was now close to the walls of the castle.
"If I recall correctly, they stated that the Bloodbound must have been preparing against our raid. I must be cautious henceforth." Kaiju mumbled, scrutinizing the burg as he got closer.
