The fourth rune pattern Lith and Solus had derived from the legacy left behind by the Fifth Ruler of the Flames, Tavar Sinak.
By itself, it looked like a bunch of complex and powerful runes that yet formed no enchantment. Yggdrasill wood had the ability to mix the energies and spells it was imbued with, so the fourth set of runes could be applied to all future spells.
By carving the most complex and time-consuming among the common runes on the Sage Staff, Solus wouldn't have to weave them when casting a spell. She only had to activate the fourth pattern and infuse the runes she needed with mana to conjure their power.
At this point, Solus could recognize the beat of her own mana flow mirrored in the one produced by the Balor's eyes and the elemental crystals.
