Celephalade is a major alliance formed in BB7.
After Celever spared Jade week 1, he decided to make a lasting connection with her, as he wanted to work with a solid shield for himself. Celever brought in his trusted ally Ephemera, and Jade brought in his ride-or-die Alfze.
This alliance was solid throughout the pre-jury phase of the game after its creation, and stuck together to keep Jade over her sister Mae on week 2, and Celever used his connection to Nick to take out Raven on week 3.
The alliance was successful early on, as Celever managed to keep Jade safe both times she saw the block, and then managed to take out an enemy that wanted both of them out in Raven. However, on week 4, Jade concluded that Celever had too much power over the game, and attempted to backdoor him. This failed, however, and it resulted in plenty of back and forth weeks with both players taking shots at one another, and the alliance was effectively dissolved.
