Annan immediately recognized them.
These constellations were those of this world!
Isaac, with the elegance and seriousness of a great pianist or a conductor waving his baton, swiftly raised his hands.
As Isaac's movements quickly extended towards each constellation,
it was like quickly typing out a complex program.
The constellations were activated one by one, rhythmically radiating a brilliant silver-white glow. Annan could even hear, as Isaac manipulated them, a harp-like clear tinkling sound gradually rising in the air.
—Annan recognized this spell.
It was the School of Prophets' "Ritual Spell: Stellar Divination."
It was not a Gold-level spell, but a Silver-level Prophet spell. Its characteristics were "difficult to learn" and "useful"... these were not contradictions.
Because this spell could act as multiple spells.
