@lxndfall requested the presence of the fifth spirit
Platinum blonde tresses waved as Elsa’s head snapped upwards. It was very rare for the river to call her into it’s depths anymore, and even so it never used her mother’s call. She and the great river had developed their own sort of language -the river using her own voice to relay messages to her and the other spirits through carefully selected tones- which could denote things such as an oncoming storm, a visitor from another forest, a need to settle harmony amongst the elemental beings, etc. There were only 3 situations in which the river would use her mother’s call, each given a higher or lower pitch to differentiate;
To return to the forest while visiting Arendelle, sometimes if just because Ahtohallan could sense her chosen fifth’s yearning for home when staying more than one day
Her sister Anna visiting, singing the call and Ahtohallan repeating it to Elsa
And the one she heard now….
This was compounded when the wind spirit Gale swirled around the young woman, seeming to direct her south towards the entrance of the forest. The spirits were all uneasy, ground shifting subtly below her feet ad she ran from the earth giants stomping in fear and the fire salamander Bruni hopping from tree to tree and simmering enough to scorch the branches without lighting them. It was as she reached the clearing gale directed her to she saw it. The being was large and rotund, slightly covered by armor and a pair of glowing yellow eyes beneath a helmet. Elsa gasped, steeling her nerves as she watched the being lazily stroll around the clearing. She had seen these beings before, nearly 4 years ago.
