Alongside the temple of Primordial Mana, this was the core temple of Manapedia. The reason for the Induction Temple being a core temple was a simple fact that this was where the 3 winners would meet the leader.
These 2 temples were just directly below the Glowing Sanctum in terms of importance and sacredness to the Mana Lords.
The ceremony was not called the Mana Lord acknowledgment ceremony, it was called the Mana Lord Induction ceremony for a reason.
In the last Induction Ceremony, Lord Main, the only Mana Lord to get acknowledged by a Celestial Beast came here and he met his leader here.
Now, Sebastian and his 2 companions were about to meet the leader also.
When all 6 of them got close to the door of the temple, the Red tier Mana Lord stopped the other 3 which was expected, allowing only Sebastian, Monolith, and Meg to go further.
Happy New Month in advance guys! Wish my luck in my upcoming exams.
