King Consort Finier was a Tulani Angel, the forest lord who swore loyalty directly to the Queen, already the most powerful entity within the Aira Celestials, with strength enough to rival that of an Abyssal Lord. The timing of his entrance was special too, just as the Petrified Thorns wall was breached, and the Demons were all squeezing toward the gap, their dense formation allowed him to inflict the maximum damage.
Like all Airas, that colorful sphere of light was his second form, in which he could emit a golden beam known as the Dream Ray. Any creature touched by this ray would fall into slumber, and if Fiends were the ones affected, these creatures, who never dream, would also be plunged into terrifying Nightmares.
