Before Erik left, Elora waved her hand and a dark green flash of light conjured some clothes onto him. "I'll join you in a bit," she smiled.
At the same time, Erik passed his armor in the corner, and pulled something out of its storage space.
When he stood outside the room, he held a memory stone in his hand. This one was yellow, a different color from the one that delivered Björn's message to his daughter. The color didn't actually mean anything, Erik simply didn't want her to get them confused.
He walked towards Alice's room while squeezing the stone in his wrist and closing his eyes in concentration. A flash of yellow passed through his fingers, and when he reached Alice's door, he opened his eyes again and knocked on it.
The door almost flew open, and an excited Alice was on the other side, ready to go. "Teacher! Is it time to get started?!"
"Yes, Alice, it is," Erik chuckled. "But remember, advancing is a marathon, not a sprint, alright?"
