Kayaba just wanted everyone to play his death game fairly. Waver just wanted to understand the gaming rig which had reduced the Heaven's Feel to mere magecraft. And Rin was only in it for the full scholarship to the Clock Tower. Unfortunately, Kayaba ended up with a cheating magus, Waver got saddled with having to rescue a student, and Rin ended up stuck inside a video game.

When the Tristain Academy of Magic is transported to the Riverlands, fourteen years into the reign of King Robert, Westeros will never be the same again.

Divine, beautiful, powerful and wise: the Goa'uld queen Amanuet is all those things. Unfortunately, she's also a body-stealing, alien snake. Poor Louise.

Louise summons a TARDIS: the space time continuum may not survive this.

Not only did Rin not get Saber, but instead she got an amnesiac Caster who can't actually remember how to cast anything except for explosions. On the bright side, they're really big explosions. Also, Louise, whose post-summoning ceremony memory seems to be missing, is not exactly thrilled that instead of summoning a familiar, she seems to have become one herself.
