Gravis just lay inside his Life Ring, looking at the bright sky. The sky inside his Life Ring wasn't real, but it also wasn't really fake. After all, to make such a Life Ring, one had to know the Law of the Dead World. So, even though it was not the sky of an actual world, it was created out of the same things and with the same Laws.
'Weapon Cultivation doesn't work for me, huh?' Gravis thought. 'I don't have Energy. I only have lightning, and lightning doesn't want to combine with anything else.'
Gravis snorted. 'Actually, the signs have been there since the very beginning,' he thought. 'Back in the lower world, when Byron gave me the Rakshasa's Saber, I managed to combine it with my lightning. No one else managed to do that.'
'Why? Because my Will-Aura was part of me, and I am lightning. Therefore, combining my Will-Aura with my lightning wasn't really hard.'
