Blue's suggestion would be to utilize the hvalus again to trace the source of unrest and chaos that they were sensitive enough to detect in the kelpwood + beyond. He, Spock, and any other telepathically/orbly-inclined sorts can work together to piece together a pathway toward the orb itself (Remi can help too if he's inclined).

Obtaining the orb is entirely contingent on the girl's mindstate + learning what deal is in play and gleaning that detail as it happens - go ahead and piggyback off this for that if u think the telepathy thing is the route to go with ✌
