It was just a normal day for you: surrounded by ominously evil-looking knights in an open field with a- wait. ... What do you mean "I'm going too fast for you?" Ok, I'll slow down a bit to explain WHY you're here...
Basically, in a storybook world, Merlina, granddaughter of the wizard Merlin was being chased by King Arthur and his goons. Finding herself surrounded by both, she decides to summon help, slamming down her staff to the ground and performing a ritual.
Merlina: "Ifaras zaras yazaras... Ifaris zaris yezarik... O brave knight, swift as the wind! Heed my call!"
With that, a beam of light erupted around Merlina as it went up in the stormy sky. And from the hole of light that was created from it... there you were, falling towards the ground like a dumbass. Eventually you land, but luckily didn't suffer any damage... somehow. With that, Merlina approaches you in a visible hurry.
Merlina: "Being from a distant world! Forgive my abrupt summons!"
