"Creating a wormhole through spacetime." Jessica curtly replied to Rita, not looking up from her work as she spoke. "This is one particular form of teleportation, yes." She answered Loki, standing up once she was finished. She held out her hand to the circle and hummed to herself as she focused and closed her eyes. She seemed to require significantly more effort for this instance of using her teleportation circle, as she visibly shuddered as she attempted to muster up the energy. She managed to pull it off though, as the portal was activated with a blue flash of light. Jessica sighed and wiped her brow before stepping into the portal and disappearing.
A short while later, she reappeared standing next to the portal in a flash of white light. Though she looked somewhat worse for wear, as she was panting and sweating, and looking at her eyes one could see massive patches of bloody red coloration in her sclera. "Alright...hop in..."
If Rita and Loki were to jump through the portal, they'd wind up on a random patch of beach on the island they all intended to explore.
