Loki's Hideout

Loki's Hideout was a temporal research facility established by Loki on Earth, in order to find a way to open a stable portal using the Tesseract.

History
Loki established a hideout with the help of the S.H.I.E.L.D. agents he managed to control upon arriving on Earth, and enlisted S.H.I.E.L.D.'s enemies to his cause, amassing mercenaries, scientists, weapons and equipment to fulfill his plan of using the Tesseract to open a portal and conquer the planet.

Loki contacted The Other using the Chitauri Scepter to inform him about his progress, taunting him that all his claims are nothing more than words until the Chitauri were under Loki's command.

Erik Selvig, under Loki's control, acted as the head scientist in the construction of a device to stabilize the portal, having learnt from the Tesseract itself how to do it, and the need of Iridium to complete the device. Clint Barton, the unwilling right-hand man of Loki and also under his control, asked Selvig about the Iridium, having investigated where it was located and how to obtain it. Loki asked Barton what he needed to fulfill his task, and he answered he needed a diversion, and an eyeball.

The device was later taken to New York City upon being finished.
