Csillag easily picks up a small, greenish crystal. Heeding the warning from the voice she makes quick time back the way she came towards the entrance of the ice caves. With a cold splash she makes it through the doorway, out of the caves. But she doesn't step into the large room with the towering Jedi. Instead, she finds herself in the sunlight in a small stone room that has lots its ceiling to the ages. A bright, warming sun is overhead, helping her shake off the chills of the ice cave, and she finds herself facing a strange contraption:
As the sounds of birds echo around her, she kneels before the device and feels the Force guiding her hand. Like the petals of a flower, her fingers open to reveal the green crystal in her palm. Using the Force, Csillag is able to gently, and purposefully, move the crystal towards the contraption before her, where it gently spins and begins to shine with a bright, green light. About the machine are various components that Csillag intuitively understands are used in the construction of a lightsaber, and the Force guides her in her efforts to build a lightsaber, moving the components delicately with her mind.

Feel free to describe the hilt/specific green-ness of the blade, etc. as you see fit -- I'll take it from there
