Jim looked up and saw what he thought was a rift opening. 
"The city is in danger...I had better see what those rifts are." Jim thought as he took his knife and carved into each of his arms. With the pain fueling his powers he desummoned his glutton and summons several powerful spirits that carry him to the city. He approaches the portal looking worried before shrugging and jumping in doing a flip as he does. He ends up in strange ally in another flying city.
"Great. Another city to help!" Jim thought as he looked around the streets.
