Getting a Bright Companion
The Two-Faced Firefly flew within his arm's reach, illuminating the area around him. The light it emitted was the brightest among all the Two-Faced Fireflies. Moreover, unlike the others, it had the option to vary light by either focusing it like a beam or spreading it wide.
When it spread it wide, Jyorta could make out things as far as 20 metres away. In the range of 10 metres, he could see things clearly. When it focused its light into a beam, it was as big as his body 30 metres away. Moreover, it was pretty clear. To Jyorta, it was more than enough.
Manipulating just one Two-Faced Firefly expended very less aura, and was less mentally straining. Pursuing efficiency based on the objective at hand, that was the motto they were taught at the military academy, hammering the thought repeatedly into their mind until they subconsciously sought it.
Even the brightest of wisdom failed when incompletely implemented.
