Diana

As you fly around the massive mountain, you scan the valleys and clearing around the peak, eyes peeled for a potential body to take for yourself. Suddenly, your eyes are drawn to a glint of metal near a small lake - squinting, you barely manage to make out that it appears to be a figure with white hair cleaning a sword, and upon flying closer you smile as you recognize who it is - Diana, the Scorn of the Moon.

Diana was sitting atop a rock over a glistening lake, holding her deadly sharp kho'pesh blade in her lap, and letting her feet dangle into the water as she carefully cleaned the sword. She was a fairly tall woman of pale complexion, with shining purple eyes marked by dark eyeshadow, the sigil of the Moon Aspect shining atop her forehead, and long white hair held back in a braid and flowing down her back. Her slender yet impressive physique was encased in a dark blue bodysuit, with armor plates on her forearms and shoulders, dark fingerless gloves, and knee-high armored boots - an outfit befitting an assassin more than a warrior, which spoke to Diana's skill with her blade.

"Skill that could be mine," you thought with a wry grin, eager to explore the world of Runeterra through the eyes of a literal goddess. After glancing around to make sure no one else is nearby, you smile, and proceed to dive headfirst into Diana's chest, drawing a sharp breath from the Lunari assassin as her eyes roll back into her skull and her grip tightens on her blade. Twisting around your ghostly form inside her tall frame, you feel her squirm and shudder as you shove your arms and legs into hers, your limbs extending to fit, and feeling her tight bodysuit hugging her curves as you assume control. Sliding your head up into hers, you vaguely hear her let out a faint moan, before your vision blinks out for only a moment, and you find yourself looking up at the skies of Targon.

As a wave of new sensations washes over you, you look down at yourself and smile, seeing Diana's armor on your new body, her blade in your hand, and your feet hanging over the side of the rock. Standing up, you take a moment to steady yourself on your new longer legs, before remembering that you should be able to access Diana's memories. You close your eyes, prodding around in your head, before what feels like a dam bursts, and you're suddenly overcome with a wave of new emotions and memories - Diana's. You smile, now able to recall her entire life from her own perspective - growing up in the Solari temple, her relationship with Leona, and gaining the powers of the Moon; powers that you could now feel coursing through your body. You could even feel her personality, able to be pulled over your own like a mask, and giving you the ability to flawlessly impersonate Diana, down to her most minute tics and speech patterns.

Opening your eyes, you smile once more, now much more comfortable and confident in Diana's body, and glance down at yourself, curling your toes in your boots and running your free hand over your toned abs.. Looking down at the blade in your other hand, you expertly twirl it around you, now intimately familiar with its ability and history of taking life, and empower it with a flare of lunar energy, watching the blade glow with power. "Fret not, Diana," you say, a hint of mischief coloring Diana's mature voice. "Just consider this a... new phase of the moon."
