Two of the heat sources had familiar shapes.
The first one was deep within the vault, and looked like a very large spider, dangling by a thick thread.
'I've seen tiny spiders… So this is the queen, perhaps?'
The second one was just beyond the stairway, to the right, visible through the wall.
'Some kind of turtle…?'
The Paru didn't spend much time looking at them.
Because the third source was heat was within the stairway, just above him.
It slithered on the wall like a snake, despite having countless legs.
More than slithering, it looked like it was swimming, due to the movement of its tail.
'A silverfish…?'
Unlike most of the Visero on Serolia who had sizeable crystals on their bodies, this one had tiny crystals, almost like fragments, covering the entirety of its body.
Despite the lack of light, those pieces of crystals glistened faintly through the darkness, as the Visero moved on the wall.
