The mark left by Rose only affected Solais, so only Solais could see Hilia.
In reality, this "seeing" was also a result of spiritual power acting on reality. It was Solais's unstable spiritual power that allowed Hilia to smoothly manifest and communicate with him.
Watching as Solais began to disintegrate and Disola rushed in, Hilia's smile never faltered.
As for the faint threats from the Elf King, she paid them no mind.
She wanted him to openly confront her!
If you've got the guts, come at me!
I may not be able to win, but you won't be able to catch me either!
After delivering that message to the Elf King, Hilia fell silent, leisurely watching as creatures turned to sand.
Solais and Disola were high-tier mages, so their demise wasn't as quick.
Having returned empty-handed from Hilia, Disola opted for self-rescue.
He rapidly notified all the high-tier mages of the Withered Wood and gathered them there, attempting to call upon the Holy Tree to elicit a reaction.
