The Glowing Sanctum.

The Mana-Lord-shaped warship spent 5 minutes before it ferried the 6 companions for the last test of the Induction Ceremony to the Glowing Sanctum.

When Sebastian first heard that the name of the core of this Manapedia was called the Glowing Sanctum, he already had an idea of it, and he was not disappointed as he was presented with vaguely what he expected.

Apart from the fact that the Glowing Sanctum was in the very middle of this Manapedia, another fact that became evident to Sebastian immediately was that the mana here was 2 times thicker than in other locations of the Manapedia.

Putting the fact that the normal mana in Manapedia was already thicker than the outside world, this meant that on entering the Glowing Sanctum, Sebastian became exposed to mana that was 6 times thicker than the outside expanse.

Still, inside the warship, Sebastian moaned instinctively as he basked in the feeling of bathing in mana of such thickness.
