Create a concept illustration of a floating island representing the sanctuary or world of three fantasy characters. The island should feature distinct elements that symbolize water, earth, and fire, integrated harmoniously. The water element should be represented by flowing rivers, waterfalls, or small lakes; the earth element by solid ground, rocks, and lush greenery; and the fire element by glowing embers, small flames, or volcanic features. The design should be detailed and imaginative, yet with no background—just the floating island itself. The style should evoke a sense of mysticism and balance, as this island is the sanctuary of the three elements. The illustration should be visually striking, with a focus on the interplay of these elements in a cohesive, magical environment.
