The Split souls looked at a massive monolith in front of them, it had different decorations all around and looked like a mystical place that had been made by ancient gods, but well, they themselves were like ancient gods, so it wasn't hard to realize this power could be part of them.
After remembering their past they felt a bit older than ever, and realized they were billions of years old, which even displayed in their status screens… but even then, their newly acquired personalities merely merged with all their previous selves and created the new perfect result.
Nonetheless, their current selves were not so different from before, they had simply become more mature and calmer, although this wasn't a big change for Ervas, and Veronica was so cheerful and often wacky that this didn't ended affecting her much either! The two were simply way too charismatic or simply were too entailed with their own new personalities.
